Ermm... either I've messed up something big, or Spine has started to mock me hard...
They say one image is worth 1000 words, so here you have 2000...:
Before rotating
After rotating
So... what the hell?? :doh:
Funny thing is that this doesn't happen to me if I use the pose tool, neither animating (fortunately). And yes, this has started to happen at every bone of every skeleton I have in this project (four in total).
If it wasn't for that it's 'only' affecting Setup Mode, I would be panicking HARD right now... :p
I'm using 3.6.10-beta and I've already restarted Spine with the same result.
Some ideas?
