It's really weird because I couldn't get that behavior. Balloons seemed to play correctly.
May I have some steps on how I may replicate it?
I just made a new project with only the mz-plugins. All is ok. So I started a new game on the firtst project and now it works with even a lot of other plugins. But it won´t show balloons on a save game. i test a bit more later because its 1 am and i have to get up in 4 hours. will be back on testing after work
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?
