Description

Loaded a new Debug World save and crashed instantly when loading chunks due to the quantum_rign block state error.

Environment

Modded enviorment and used many times before. This was testing in Single Player and other mods are listed here: https://git.io/fNKTm
The complete crashlog: https://git.io/fNKTs

• Minecraft Version: 1.12.2
• AE2 Version: rv5-stable-11
• Forge Version: 14.23.4.2745

This should only happen when the TileEntity is missing, which either points to a corrupted save or something trying to render the chunk before its loaded.
Have you tried without optifine? Also, betterfoliage shows up in the trace, try without it.

Does it detect if the tile entity is there, by checking the block next to it? Because if so, then that is the exact reason why I was crashing because every block in the debugging world is spaced one block apart.
