so i was making an animation for a thing and for some reason some of the layers disappeared.

well its not really dissapearing but more like hiding my layers i guess. my images are imported so and have a completely transparent background. the main problem is that the transparent part is hiding the other layers behind it and it didnt do that until there were too many layers i think (27 layers). i found a solution to fix it by going to view>preview mode>fast but when i try to export it as anything the part that was being hiden was is being hiden again. gif, png, and symbol, etc. cant really use the animation properly if its doing this
