I imported some props that I animated and they were working great. Then I saved the file, reopened it later for editing and one of the props changed in a very strange way. I've attached a screenshot of what it looked like previously (top) and what it looks like now (bottom).
I'm also experiencing props disappearing completely. I have a file I saved of a previous scene and opened it to make a few edits per client request and three custom props disappeared from the timeline. They were still available in the Content Manager under Custom Props but I had to add them to the timeline and reanimate them all over again. So much lost time. Yes, I did save it after all of the work was done so it wasn't a save issue.
