I've been wondering about this for some time. at first chalked it up to something I had done, but have noticed it more and more with different characters, some not created by me at all.
 
Sometimes, I open a scene, and play back animation, and the character geo, blows apart, becoming a tangled unusable mess.. bind posing, or reset actor will do nothing to fix it.
 
Sometimes I open a scene with no animation at all, just a rigged character. I may move a control object, or rotate a bone.. same deal..
 
the fix is pretty simple, just offload the weight maps to a preset, and re-envelope, but for the life of me, I can't figure out whats going on. I've seen it on both 32 bit and 64 bit systems of late.
 
Is anyone else experiencing things like this?
 
Its only something that seems to have popped up in recent versions, maybe post v5.11
I wonder if its related to that timeless  envelope> reassign locally bug?
 
Its something that has yet to be fixed, and can be worked around by offloading and reapplying weights via preset, so I'm guessing they must be a symptom of something else going on.
