I had this happen some days ago.. Without apparent reason. ONE scene out of several loaded without the morphs. Luckily I had an almost identical scene saved that worked, 

 

The pmd's were present at the same place at the scene. I haven't turned them off.. (they're handy if you actually want to share morphs) 

But I suspect a minor bug somewhere. Mine was PP2014 btw. not 2012.

You just can't put the words "Poserites" and "happy" in the same sentence - didn't you know that? LaurieA
