I made a project with EaseTween Behavior since 6/13/2012.
After twice updates of this behavior,
this project 3 months ago can't be opened today, it shows some action ID lost.
It seems that the new version of EaseTween is incompatible with old ones.
Fortunately I found the oldest version of EaseTween in my computer, so I can fix it.
Maybe it will be better if there's a list of downloadable versions of this plugin,
especially when there's any breaking change.
Thanks, I love EaseTween.
Keep the great work!
