Summary0001648: NullPointerException in loader
DescriptionAfter updating to version 752, all machines containing Redstone Signal Inverter Upgrades throw an exception. The server continues without crashing, but all upgrades disappear from those machines (including other kinds of upgrades). The error mentions ChickenChunks, but I don't think it is related. Log attached.
Steps To Reproduce1) on version 751 or below, insert a redstone signal inverter upgrade into a machine
2) stop the server
3) upgrade to 752
4) start the server

Player changed a lot of both the upgrade and redstone mechanics in 752, this must be a side effect.

Not sure if this was intended to be fixed in 755, but I can confirm the problem persists.

i also got this crash report:

i using 754 version

Does this happen when you have machines with redstone signal inverters added after build 751? That will determine whether they're completely broken or just broken updating.

Reproduced per suggestion above.

1) Updated to 755. Addons disappeared.
2) re-added the redstone signal inverters and other addons
3) stopped the server
4) restarted the server. NullPointerExceptions again. Addons disappeared again.

Yeah, it's confirmed by multiple people redstone signal inverters are broken and it's not just updating past 751 that is causing it once.

I even didn't put the redstone signal inverter inside the machine

I can confirm we are getting the exact same NPE.

Confirmed fixed in 757.
