Ohhhh yeah I see what u mean

No im talking about the hand tool thingy that you can move your art around

Yeah, the bucket tool, right?

To fix it all you need to do is use that tool Between Eraser and Color

I found out that is prob bc of using the bucket tool
At least that’s what happens to me 💔 what I do is just undo until the filled space is gone and I just fill it again
