or whats causing it?

You can "MCedit" this issue. There is enough information in that crash log - exact block location and what is causing issue. Just load world or region with this block and delete erroring one.

ok, has number 2122 been fixed yet?
Is this a confirmed bug? i saw one other person having similer problems.

i think im down 1 version on forge multipart, do you think that would matter at all?

Also check what i posted again, i updated it

It looks like a generic Multipart corruption

No clue how that could happen, but I added a null check.

thanks!
