Method setColor in CCProgressTimer and Bezier Curves

Hi, I have updated my code to version 2.1.5 from 2.0.4 and I have found that setColor method in class CCProgressTimer does not have any effect, I have read that in cocos v3.0 this issue or problem has been fixed, but I can not update my game to that version right now… Is there a fix for the version I am using?

Also, I have found that now some weird movements appear in Bezier Curves using the same ccBezierConfig and CCBezierTo action, sprites movements are not following the described curve…

Anyone knows how to solve those issues?

Thank You!
