lokesen - very odd, I cannot think of any change in r107 that would affect this. Anyway, glad to hear it's sorted, so closing.
No not according to the changelog.
I only found one animation that kept looping no matter what I did. I solved the problem by making a new sprite and copy over each frame individually and then it worked fine. All setting and event was the same, except from the new sprite name of course.
So it must have been some kind of error in that sprite.
Now everything works.
I'm actually a bit of a nervewreck everytime a new beta comes out, with almost 3500 events in my game, something is bound to go wrong with each new beta. But if I just waited for the stable release there would be too many changes to keep track of.
So far it has been quite easy and worth almost every update.
Keep it up! :)
