Most likely related to this 2 year old bug (fixed in r100): https://www.scirra.com/forum/viewtopic.php?f=152&t=70936&p=598242#p598242
Frames of a sprite were replaced by other frames in the sprite after I rearranged them and then saved and previewed. I believe it must be associated with the bug fix from years ago?
- Opened up a sprite with frames of animation in it
- Using the mouse I dragged the frames in the animation toolbar many times so that they would all become before/after other frames
- Saved the capx
- Previewed the game and noticed some of the frames were messed up and duplicated (I thought I had made some mistakes in my code)
- Opened up the sprite again and noticed many of the frames of animation were moved/gone/replaced/duplicated
What the frames looked like before I saved (and after I remade the sprite):
What looked it looked like after I saved (the bug):
As you can see, after the bug occurred nearly all the frames had been rearranged into a different order and some of them had their image replaced by other frames.
