Found a bug:
"Play current animation" appears to always play from frame one, even if you specify a different frame to start on with "Set animation frame."
Could we get a hotfix, or should I post this as a bug report?
Edit:
Oh man, it even does this in 97.5. I never noticed before, I've never actually attempted to do what I'm currently doing.
I'm making a series of ocean wave sprites. Each animation loops, but each one needs to start on a different frame in order for them to look wavy. No matter what frame I set, they all revert back to frame 1 on start. I guess I'll make a bug report after all...
