Hi,
I'm a new spine user, and while animating a character I found something strange happening.
I originally made a walking animation, and wanted to try a running animation. My walking animation cycle was 12 frames long, and I copied those frames in a new animation, tweaking it and compressing those 12 frames into 9 frames (I selected all the animation frames and pushed them from 12 to 9 frames). When I pressed play, one of the arm bones in the dope sheet started creating keyframes on every cycle. I stopped the animation, thought it might have been my mistake and erased those extra keyframes. When I played the animation again, they started showing up again the dopesheet. Those keyframes are not created on the 1,2,3,4,5 frame mark, but in between (as shown in the picture). I tried closing the and opening spine, but those new keyframes are still there. I can select them, move them (to the closest full frame), and erase them but they will come back after pressing play again.
The file I'm running is a series of very big png's, there is FFD on the arm mesh, but I erased all the keyframes to see if that was the issue and it didn't help. I'm animating the arm with FK (there is no IK on the arm)
Is this a known bug? any solutions?
