> Did you do anything like rename or delete to the files of your project before you opened your project in C2?
No. This problem appeared after I added a couple of events and launched a preview.
I've already solved this issue, but let it be for your information :)
This is a major bug for Ashley, and my only wish is to help him iron-out this bug! <img src="smileys/smiley17.gif" border="0" align="middle" />
Did you add any new animations or re-name or delete any? before debugging.
