It just happened to me today as well! First of all though webvogel THANK YOU for such an awesome environment. Finally my fantasy characters have found a place to meet :) Now, here's how I solved it just in case someone wants a quick fix without resaving. I first brought in the character(s) I wanted to use and then imported your PZ3, it's important to import and not open or you'll lose the characters. For some reason it worked. I, too, thought it was a memory problem ravenfeeder but I had the same things again in the scene and everything was fine so who knows?? Hehehe, I love a good mystery though :)
