Crash NullPointerException

[Hyderatic]

I have a feeling that the crash got something to do with Thaumcraft though i don't want to remove it. Maybe there is a different mod causing that crash.

java.lang.NullPointerException: Initializing game

Yes, it has something to do with Thaumcraft. Try updating it to the latest version for the game version you're playing on, or remove it.

Thaumcraft is in the latest version, though maybe there is some other mod causing the crash? I'm making a magic based pack and Thaumcraft is a major mod for it.

It looks like another mod is sending an IMC (Inter-Mod Comms) message to Thaumcraft with an

ItemStack

that has a

null

Item

. This could be a message telling Thaumcraft about a crop that can be harvested by Golems or about a crop that shouldn't be affected by the Lamp of Growth.

 

The crash report doesn't say which mod sent the message, so you'll need to figure it out yourself. The most likely culprits are Thaumcraft addons that add crops of some sort.
