Version Information

Minecraft version: 1.12.2 server
Forge version: forge-1.12.2-14.23.5.2859.jar
sponge: spongeforge-1.12.2-2838-7.4.7.jar
When I tried to use Spongeforge with Cubachunk it crashes
debug.log
When I'm without a spongeforge, it doesn't crumble.

CC doesn't and likely never will support sponge unfortunately
