Door Bug/Incompatibility?

[Sporeman]

Currently, I have 2 mods, BTW and More Creeps and Wierdos. Whenever I try to operate a door, my game says "Saving chunks", then crashes. This may be the situation with other blocks, but so far all I have tested is the door.

Thanks in Advance.

Have you got MC forge?

[Sporeman]

Yes, I do have MC Forge.

EDIT: Wow, I thought I downloaded that. For now it seems like the problem is fixed. Thank you!

EDIT2: Oh great I just made myself look stupid to FC D:

Look like an incompatibility between Mo'Creeps and the Forge. Might want to talk to the author of that mod about it.
