I've been trying to use the built in Platform Engine and it was working fine until I added animations and found out about setting collision masks. I found a video on Youtube to make one mask and share with all the frames of all the animations. Video link
I followed the video and upon sharing the masks, all of return to being blank. I've set each frame individually and it worked until I closed Construct and opened it to work on later.
I can't even start trying to design levels or anything since I fall straight through the ground on start up. I don't know if it's just my computer, me, or the file itself.My cap file
