There is a crash dump from single player. Sorry about not removing foamfix.

Will post new dumpbin if it looks different without foamfix installed.

edit: yup, still crashing. And dump looks the same.

Still appears to be an issue in the latest chisel for 1.12 (0.0.14.18), almost identical crash log (also multiplayer)

Context for the crash using a diamond chisel to chisel cobble to a chisel variant. Accidentally took too much out of the storage drawer so my inventory was full when I went to shift click the block I wanted from the chisel gui.
