That may be the issue then! I assume something in Prime Parallax doesn't work right for saves. I'll try that out asap when I wake up!
I tried a lot of combinations with different events on a new project and the project where the ballon-ani was missing (from the start, from new saves and I even made a save on the same position as last time). I was not able to reproduce this issue. Only on the saves from the first project. and even there it´s only missing on the player char. The balloons are all ok on other events. But on the player it is not only the balloons but all animations. So maybe it only occurs while actual building the game, installing, deinstalling and testing things out, because on the new saves the plugin was already there from the start?
Sorry for the delay (my cpu cooler died and my gpu also kinda went oof)
Anyway I've released an update that should address the problem!
Thanks for your help and patience!
