I've run into an issue a couple of times where I delete a keyframe, but Spine seems to think there is still one there. I've attached an image. There was 1 keyframe at frame 25, I deleted it but the red dot remains in the dopesheet. Exports will also include those extra frames, even though there is no keyframe at frame 25.
This happens occasionally, and I haven't been able to find a fix for it. The only way I've found to fix the issue is to completely recreate the animation, which (at this point in this project) would be a MASSIVE undertaking. I have 80+ skins, most with special keyframes on this animation.
Does anyone have any ideas? Anyone else encountered this bug?
