I've never seen anything like this before but animate has somehow not saved parts of my project but still saved others. You see yesterday when I was working on my project I made sure to save and close it like I normally do. When I opened the project today I've found that some of my objects, which were colored in yesterday, are now back to just being lineart. The strangest part is the fact that coloring and animation that I did later on is still intact and perfectly fine. Needless to say, I'm pretty annoyed and also very confused as to how something like this could even happen.
