The mod is crashing very frequently with the "Ticking block entity" error, always about 5 minutes after placing a mechanical block everyone in my server will crash except for one and we have to have him run over and break the block for us before we rejoin. This is making it a major hassle using this mod and we probably wont be able to use it until this is fixed. It happens in single player as well as multiplayer. Here is the crash report:

This issue has been closed since it has been inactive for 3 weeks since it was marked as stale.

Happens with any moving block, not just mechanical press, only if the chunk has been unloaded, it is enough to stop the mechanical block from moving, you don't need to delete the block.
