Thank you very much. (btw when deleting the keyframe in the project you provided, it still crashes for some reason)
Those other bugs happen to me all the time. When I parent an image to a bone, most of the time, that will make some (sometimes a lot of) objects in the hierarchy disappear.
They reappear after being selected in the main window.
The filtering looks kinda weird in the editor. It looks right when rendered out, but the image in the editor looks very strange to me. If this is due to optimization, it would be cool if the "high res" filter could be used when the animation is not running. A preview that looks like the final result would be cool, too. This is what I mean:
PS. You are right about the sword. I haven't started to actually animate anything, or I would have noticed :).
btw: what about that Right.scml_000.png thing?
