Recently I reviewed my creations and deleted several creatures. One of mine was in my game, but after the deletions I noticed that it wasn't there anymore.                                                                                                                                                   After the initial creation of that particular creature, I made a modification and saved it separately. I then deleted the first one. It was the first one that was in my game.                                                                                                           
I then realized that by deleting it from my creations page, I had deleted it from my game as well. Has anyone else had a similar experience?
