Please find attached my spine.log
System: MacBook Air, El Capitan
Steps to recreate:
1) Open Spine pro demo (spineboy) project
2) fiddle with rotating stuff
3) mash cmd+Z repeatedly
Effect: Crashes and Closes, get mac system crash report.
Note: This also happens frequently and sometimes even when I don't cmd+z, but cmd+z seems to be the thing that gets it to happen the quickest. but no matter what I do it happens within 3 minutes of use of just rotating and fiddling.
Thanks!
Edit in case it is helpful, Chris (my workmate) doesn't experience this on his windows machine. Only on our macbook air.
