We are running version 2.1.27 of Spine.
We were able to narrow the problem down to Images being off in the setup, or being turned off in the animation. Now that we simply moved the image out of the way in 1 frame the bug stopped. This is a quick fix because we are low on time, but is quite a problem for future animation. 🙂
The animations run from character rigs to slide's of images to create a movie animation.
