Hi there!
I uploaded a new version 5.0.7, I hope it fixes the issue!
But, I have to say, I tested on the Mog Sample project, and I didn't manage to trigger the issue.
I believe that maybe you downloaded the project from somewhere else, or Mog updated the project and forgot to change the version number.
I'm saying that because I downloaded his project, and your plugin was not the same as the one in the sample project.
I know that because on your error log it says on the second line:
"at Spriteset_BattleHudBase.isAnimationPlaying" on line 2153
But, on that line, there is nothing but this "};"
So maybe you can try download that sample project again and updating your MOG plugins ^^
Anyway, hope it helps! :D
