GregTechCE
[BUG] crash updating to latest gtce with techborn
actually reverting back did nothing - seems to be a c rash with any gregtech and galacticraft?
Any particular reason why you think GregTech has anything to do with the crash? The stack trace looks unrelated.
The actual error is:
java.lang.RuntimeException: One of more entry values did not copy to the correct id. Check log for details!
at net.minecraftforge.registries.ForgeRegistry.sync(ForgeRegistry.java:549)
The only thing in the log relating to registry sync is this warning:
[01:16:07] [Client thread/WARN] [FML]: Registry Block: Override did not have an associated owner object. Name: plustic:plustic.molten_titanium Value: Block{minecraft:air}
The reference to "minecraft:air" suggests it wasn't registered properly, but I don't see any error further back in the log that gives a reason for this?
This doesn't look like a GTCE related problem.
The reference to "minecraft:air" suggests it wasn't registered properly
"minecraft:air" is used as a block or item not found/default value by minecraft.
Suggestion: Since you have a large number of mods. It might be that updating or adding mods has led to having more than the 65535 blocks/items allowed by 1.12 vanilla minecraft.
You could try adding this mod which removes that limit: https://www.curseforge.com/minecraft/mc-mods/jeid
But make sure you back up your world first. The mod converts the world to the 1.13 save format and this operation is not reversible.
