My animations that use color keys for fading became messed up lately:

Most of the pink timestamps shouldn't be there - there was only a simple fadeout with 2-3 key frames for color.
Even old versions of the project from my backups are affected (ones created with old Spine version, before this problem started occuring - so I suppose the project files are not corrupted).
And instead of fading out during the animation the images now flicker (in the places where pink keys are) and stay visible at the end instead of fading out. can send you the project file to look at if you want.
It happened some time ago (maybe even a month, it was some time since I have done anything with this game), but I thought it was a bug in my code causing the flickering. Only today looking for the problem have I noticed that the animations are messed up like that in the editor too, not only at runtime.
PS. I have e-mailed you the affected projects with images, maybe that will help. They are definitely not loaded correctly since it happens even in my old backup projects made very long ago.
Any update on that? If more info is required let me know (I could for example draw on the images to show which keys are incorrect). Loading those projects in older version of Spine will probably show the difference more easily.
