Summary0002027: Cables and maschines don't input or output energy, after a chunk was unloaded and loaded again!
DescriptionEvery time I left the server (or simply if the chunk gots unloaded), every cable and every maschine has to be replaced in order to make them transmit/accept energy again.

The cables also do look kind of weird, cause they are placed next to each other but they wont connect. So they do look like they are only a dot.

After breaking only the cables and place them back down, they connect again to each other but not to the maschines.
Steps To Reproduce1. Connect to your server, that is running IC² on 1.10.2!
2. Place down any IC² maschine and some cables!
3. Left the server and reconnect!
(But wait some time, to make sure the server unloaded the chunk!)
4. Bug ready to be seen!

5. Like explained, you can break everything and put it back down to fix it.
Additional InformationI've tested this with and without other mods installed, so the bug also appears with only IC² installed!
TagsNo tags attached.

What versions are you using?

I can confirm this bug. It happens to me too with the latest 97-ex110 build of IC2. The fastest way to reproduce this bug is on a singleplayer map and to tp to a far away chunk and then back while a machine is running. You'll see that the machine shows to be active, but if you check in the gui the values are all frozen. You can even put the items out and back and the machine progress won't update anymore.

It's like the Tick-System is being halted. I'm not sure but one time even Minecraft furnaces froze when they were in the same chunk like the IC2 machines.

This bug happens to me as well, hopefully this helps.
My original multiplayer server was on forge version 1.10.2 12.11.5, and Industrial craft 1.10.2 - 2.6.15 (if I remember correctly). All of the machinery in spawn chunks worked ok.
One of the players reported this issue at one point, but it was fixed by him relogging. Later on he relocated the machinery and problem did not pop up again.

Then three days ago I started a new base some 3500 distance from spawn, and the new machinery was affected by the same bug as in the above picture (with server reporting that 'wires are already placed, aborting.' when I tried to log in near the new machinery). All of the connected machinery and transformers were not connecting as they should either to old or newly placed wires - all of the old wires became singular (no connections). When I removed wires and placed them again, they refused to connect to machines and transformers but would extend towards nearby old wires (which would not extend towards new wires) - all the wires needed to be removed and replaced and all of the machinery also needed to be removed with a wrench and placed again to start connecting and accepting energy from the grid.
Oddly enough, wind generator performed as it's supposed to and kinetic generator received kinetic energy, showed correct electricity generation, but the connected transformer (512->128 MV transformer) refused to connect to wires and forward this energy. The transformers both had to be removed and placed again - MV was connected to kinetic generator and LV transformer down the line connected to machines.

I updated both forge and IC2 to latest version:

Forge: 1.10.2 -
Industrialcraft 2: 2.6.101-ex110.jar

This did not fix the issue, it's still there. When I go away from the machinery and come back after a while, I will often find the whole network segmented with no parts connecting to one another.

I tried placing multiple smaller networks in nearby chunks to see if it was chunk based, but all 4 surrounding chunks had the same problem of wires segmenting. Four out of four chunks seems more like some rule rather than random chance.

When I tried to relog with the client to the server, sometimes some wires would fix themselves, sometimes all of them would fix themselves.

Restarting the server connected parts together properly as well.

All until the next time when I move away from the machinery, when it nearly always disconnects again if I go far out for an extended period of time.

I tried increasing and lowering view distances to see if it would help with anything, but problem remained.

I will try another experiment today with many wires in many chunks at various places around the map to see just how frequently this happens and if it's a near-far thing from the spawn chunks or not. I can include a screenshot next time it happens...

Adding to this issue:

I can't believe how few people I see mentioning this. I chatted on IRC FTB and several people knew this was a problem and that there was no current fix or workaround and yet here's a bug that has been reported for over a month and it's still unassigned?

I am unsure what the exact version of Industrialcraft I am using is but it's the version included in FTB Infinity Lite 10.2 (modpack version 1.2.0)

The problem is exactly as Vorheart describes.
One thing to add however. Not only do machines and cables disconnect and stop working until broken and replaced everything, taking a lot of time and making the player lose a ,lot of EU from breaking the MFE / MFSU's, but also, I had a copper insulated cable running from MFE in base to Kinetic Windturbine and not only were cables disconnected, they completely disappeared! Over a length of about 30 blocks no cable to be found anywhere.

Hope this gets the attention it deserves because there's a modpack out there (AND users that downloaded for custom packs) that are rendered with a pack where it's unplayable / Industrialcraft is unusable.

The second problem you are naming with the cables disappearing is most likely caused by the kinetic generator emitting High Voltage, while the copper cables can only transfer Medium Voltage, so they disappear, because they can't handle the energy flowing through.
The first problem however is known, and I investigated this a couple of times now, but due to some real-life things, I don't have the time to investigate this more. It will get fixed, once I have some more time again.

Thanks for your reply!
I should have thought about that (the cables).
But still.. Losing 80% of all energy stored bc of a restart of logging out is not fun to play :). I respect you needing time for yourself though so I wilol be patient and hope for the best (for you too).

Also.. obviously but to be sure you know, upgraded to modpack version 1.3.x (industrialcraft-2-2.6.105-ex110) and problem still persists.

This is now also happening on my server, strangely enough even after reconnecting and the cables are connected energy is still not transported.

I attached a screenshot of what it looked like before I rejoined.

Forgot to mention, this is happening on version industrialcraft-2-2.6.105-ex110

Sometimes if leaving the server and waiting long enough that the server unloads the chunks the cables might be fixed and work as intended.

Maybe has something to do the way IC2 is loaded? I'm no mod developer I wouldn't know.

Could you please prioritize this issue a little bit more?
As long as this bug exists MC will be unplayable for me.
It's not only the IC-Machines that won't work properly anymore, the whole tick-system doesn't work properly too. At least a workaround would be nice.

As long as IC2 is closed source, we can't do anything ourselves, so please do something about the bigger bugs first before implementing new features. I like new features as much as you do, but I can't enjoy them if the core functionality is unusable.

I can confirm this as well, it just started happening on my Single Player world.

It may or may not be related, but it first happened right after the Wooden Rotors in my Wind Turbines broke.

Logs! I searched the FML log for IC2 and found some information relevant to the issue.
Hopefully this helps solve this.

Can confirm for 2.6.194.

It's very annoying to break those every time I go far away or re-enter my world...
