2.68a Rigid Body Cache Won't Revise?

Hi All,

It seems like there is a problem with the rigid body cache system. IT won’t seem to let go of a previous cache even if I free a bake or rename the cache. I change gravity Z from 2.0 to 0.0 and my objects still rise.

What is the trick to getting the cache to revise and update correctly? Or are we facing a bug here?

Where is the cache actually stored on OSX? I’d love to just delete it if I knew where it was…
