It was when I was scrubbing the time line to check it, and I noticed a bone was moved, only on that frame. So I must have moved it on accident, but I was able to move all the other bones, not that one, which is why I thought it may be a bug, if it is, I will send you the file. Let me know were to send it, if it sounds like an issue. It did to me, since I can move all the others besides that one. I will check it today, its for a school project for my Team Project for my BA degree, so its important I get this working correctly. I still need to add it to Unity and 2d tool kit, hopefully with no issues, since I have less than a week to get this going.
