When I try to join the Minecraft server that I used to play on my game crashed with the following crash report: https://pastebin.com/bc8hhkjn
If I am right in reading the crash log it is cause by the crank of a grindstone that my friend build in our base.
I am playing the modpack All of the mods 3 v.5.9.4b

• Minecraft Version: 1.12.2
• AE2 Version: rv5 stable 11
• Forge Version: 14.23.3.2678

I do not see anything obvious causing it. Currently I would guess it is either just some random crash due to data corruption or some othere mod interfering with the rendering. Best idea would to reduce the mods when trying to reproduce it.

It was already fixed by removing the crank but I hoped that sharing this would help finding the cause for it. If you say that it might just be some data corruption then it is probably not reproduceable.

No idea. The render is pretty simply and just forwards the model/blockstate and such things to the minecraft/forge pipeline.

In case of the model and blockstate, this is unchecked by us, but we just acquire them from the normal minecraft/forge methods and if they do not return the correct data there is something seriously wrong and we should not even try and recover it somehow.

The other data either is related to them or would crash at some completely different point. Basically in our renderer and not somewhere down in forge/minecraft.
