Hi, I find this weird problem where I can't select any mask's path below another mask layer. Example:
I try to select mask 3's path from comp viewer but mask 2's path was selected instead. Mask 2's path will even selected when I click outside comp area. By the way, not whole path was selected but only some vertexes/points (2 or 3 randomly).
keyframes added to scale and stroke effects.
I solved this problem by removing all the keyframes, effects and masks, then re-paste masks. However I have no idea what cause this problem.
