All entities move around for no reason and cause extreme lag?

[flamez3]

There is one or more entity(ies) causing some physic bug that removes everything of the map and causing an infinite collision. Check this video out: http://www.youtube.com/watch?v=Eb0b9FqyKRo
See how laggy it becomes after the physic bug.

Check your entities, make sure nothing is overlapping.

Yeh I thought it would be something like that. I had alot of stools and they were all copied and pasted from one-another, I'm guessing the original was overlapping something. Thanks for explaining that further
