Hi!

I am using Spine's latest edition (4.0.31) on windows 10.

I pressed T (previous animation, I assume) accidently in the animate mode today and Spine just crashed. I tried pressing T on other project and it doesn't crash. But only in this project it crashes every time.

Here's the log file. If it's necessary I may provide the project file later. Thanks!
