Rigid body objects may go insane if project is moved into 2.75

Rigid body objects may go insane if project is moved into 2.75 if they have a rigid body joint,

solution? add new object, grab data from old, delete old mesh.

and the fix

feels kinda neat to find a bug, find the cause, then work around it before anyone can even look at the
bug :smiley:

Not an excuse to simply decide to have the bug stay unfixed, otherwise youโ€™re projecting the idea that instead of the devs. fixing the bugs, you expect everyone else to workaround it as well.

I reported the issue(first) and then looked into what exactly as going on, then worked around it :smiley:
