When a fairly complex set of simulations is set up (3 - 5) on a single figure after some repeat simulation or draping I keep getting a radiant geometric explosion from what appears to be the teeth geometry which is not undoable or reversible so the scene becomes useless and I need to go back to last saved and start again.

I don't think this was happening prior to installing service release one for P7.

It is happening with monotonous frequency and is very annoying.

Anyone else experience similar?
