After activating a statue, turning it into the mob, many options are removed from the chisel menu, notably the quartz, basalt, emerald ore, lapis ore, and mossy variants of Alice. The only way I could find to add them back is to restart the game, the bug perceivers through to other worlds.
I'm experiencing this on 1.21 Neoforge with version 1.0.2 of the mod
neoforge version 21.0.167
