Parts of my drawing suddenly filled with black.

Hey, so I've noticed a trend while working on backgrounds for my videos. I'll get one done and it'll look great. I'll save then when i log back in the file has decided to fill in random parts of my drawing with black. Here is a pic to show you what i'm talking about

This is a mild example. Sometimes When i re-open a file some of the lines are all broken and look like someone raked a piece of charcoal over a paper. I'm tired of having to go back and manually color in the blacked out portions after I know I saved it without it being blacked out. Can someone tellme what's happening, or is it just another adobe-glitch?

Must be a glitch.

Don't know what the structure of the background is, but from general experience, such 'glitches' happen when a drawing gets too complex with many points.

Best practice would be to have the elements separated on multiple layers, symbols and so on. This will, hopefully, reduce the occurrence.

What I say is purely from past experience with various versions of Flash. I don't use Animate for serious work (unreliable and unpleasant), so my observations are just from random testing.

I am having this issue as well. It is extremely unprofessional and ametuer that Adobe has not updated this. It is scene/app breaking. My sene is not complicated at all yet this error is making everything take 10x as long. This needs to be addressed and fixed.
