skarasuko This is a pretty major bug that needs to be addressed asap. The speed of the animations somehow got 2 times slower, but this is an estimate so the frame speed is unknown. There also seems to be some stutter while playing.
Luke Hello, thank you for reporting this. I've created a Github issue for this bug here: https://github.com/EsotericSoftware/spine-editor/issues/710 You may track the progress from the Github page; I'll also post here when it has been fixed.
Nate Yikes. We missed this because we had animations with audio, which aren't affected. :wounded: It's fixed in 4.1.13, available now.
