This most likely is due to when I cleaned the level.dat file of missing/dummy blocks but I thought I'd post this here in case that speculation is off.

1.12.2 on forge 2730
Breaking a block causes my game to crash on a server (no one else seems to have had this issue though and I cleaned the level.dat like 3 days ago). Particularly bionisation3's machine blocks. The disinfector and DNA constructor in particular are the two I broke. Both threw out an error with foamfix's name on top. First I thought to contact foamfix but according to a duplicate issue from a few weeks ago they redirected me here as the solution. Is there any way to fix this or will I just have to break all the machines (total of 5 of them) and crash every time before placing them back down?
I'm betting a lot of chisel's blocks have been affected(from the looks of one crash) and the entire factory is made from chiseled cobble...

Duplicate of #7 . This was already fixed a few weeks ago, update to the latest version of the mod.
