I haven't posted anything in a while, so I thought I would report this annoying thing I found. When messing with this character I made in Blender, I would put him into a scene, decide I didn't like him, and go back into Blender to edit him. I would then export him again and overwrite the original character. If I overwrought the original character with a new one while the old one was still part of the scene, my original character would become this horrible distorted thing that could not be deleted. Furthermore, my original character prevented me from running my game, deleting stuff, and saving, probably because he was angry at me for overwriting him. I got around this by copying and pasting my entire map into a new file. That's all.
