So I've been trying to fill this image but I can't and when I select the lines some of them appear to be normal fill strokes but some of them have vector paths around them? and I can't fill those ones in. I have also seen a classmate of mine with the same problem! Is there a way to convert these vector (?) paths into normal fills again?
wait no...got it.. you just right click > break apart
The reason you are seeing this is because you turned on Object Drawing mode at some point. It's a sub selection of the brush tool. Toggle it on/off with the "J" key. It has value if you want your shapes/strokes/drawings to be "protected" from other shapes.
