There are several animations that I've made that don't work, while others that are exactly the same (other than the actual picture) do work. They show the first frame, and then don't play anything else.
I have it set to this for all of them, and want to switch between them (it's a small, medium, and large form of the player) when you gather enough items. Like I said, it works in every way, other than actually playing the animation. The medium size animation does actually work properly, while the other two don't.
Lower Speed: 15
Higher Speed: 20

Loop is checked.
(I'm using change animation to change it, btw. I've tried everything else that I could think of, and this is the only one that even sort of worked.)
