So, I noticed when I saved a file, some things changed from when I reopened it. Like animate seemed reposition some drawing frames in places I didn't originally have them in. Like an object I originally drew in the center got moved to the right side. I'm perplexed on how this occurred, and I'm worried that animate might mess up more of my files in the future, so I would like to figure out what's going on.
i don't know why that happens (or even if it happens because of an animate issue), but you should be saving your work periodically with increasing version numbers appended to your file name so you can return to a correct version.
