Summary0001962: Server Only Crash On Startup (API Errors with Ender IO)
DescriptionI have recently included IC2 in our modpack located here - currently under review at the time of this report.

Have tested the pack in my dev build and it loads perfectly fine but when trying to start the server the server crashes each time.

Once IC2 is disabled server side the server starts with no issues. This crash does not occur when starting the client just the server

IC2 Version industrialcraft-2-2.6.30-ex110
Forge Version

Attached are the Server Logs and Crash Report
Steps To ReproduceStart server with my pack as a server will crash each and everytime.

Minecraft Version1.10.2

Seems that this crash only occurs on worlds that were made before IC2 was put in the pack have tested this on a brand new world with no issues. I do not wish to reset the current world is there anything that can be done to rectify this or is a reset the only way.

Try using build 32 or later. If your log gets spammed after updating, please send me the log file.

Using build 37 worked like a charm thanks for the help with this

The only issue is that since the build that is being used is not currently on curse they are saying i am unable to include it in the pack is there anything that i can link them to to allow this version to be put into my modpack.

Still getting some client crashes not sure if it is IC2 related but the stack trace does report IC2 but i believe its more a machine power craft issue relating to the API

This seems to be client side only and seems only happening while we have machine power craft mod installed on the client. Do not know why its not affecting the server.

Mod Dev for machine power craft is difficult to deal with in regards to these errors

That is a different bug.

I am more wondering if it is a IC2 Bug or machine power craft i rather not raise another issue if its not related to IC2 as i was reading something regarding this in the IC2 forums and it mentioned it was due to the API with machine power craft but i am wondering if it is or not.

But I will raise another issue to make it easier on you guys
