Sorry for the delay.
Thanks for sending the reproduction files, I just had a look at it. Unfortunately I could not reproduce the problem you were showing. Which version of the spine-unity runtime (name of the unitypackage, also listed in Assets/Spine/version.txt
) are you using? If you are not using the latest unitypackage, could you try upgrading the spine-unity package?
Could you please also show the content of your Console window in Unity when this problem occurs? It most likely shows some error messages there. If you could please copy and paste the first error message that you see in the console here on the forum, we could have a look at it and potentially prevent such problems in the future.
