After upgrade to Unity 4.1 yield not working?

I didn't have any trouble with WaitForSeconds while changing of version. Are you sure you didn't change anything in your script ? $$anonymous$$aybe you can post the part that is not working so we will be able to help you...

Nothing is changed in scripts. This is original main script:

 // Original script in 3.5.7
 function SpecialAction (expPosition :  Transform, distance : int) {
        CameraShake (expPosition);
        // Other stuff
        ... 
 }
 
 function CameraShake (shineExpPosition : Transform) {
        ...
        yield WaitForSeconds (0.2);
        ... 
 }

I resolved this with adding another function inside main script that is calling function with yield statement like this:

 // modified script for Unity v4
 function SpecialAction (expPosition :  Transform, distance : int) {
        YieldCameraShake (expPosition)
        // Other stuff
        ... 
 }
 
 function YieldCameraShake(expPosition) {
        CameraShake (expPosition);
 }
 
 function CameraShake (shineExpPosition : Transform) {
        ...
        yield WaitForSeconds (0.2);
        ... 
 }

Only thing I can think of is that this is hapening when SpecialAction is called from another script (enemy or bomb) and before yield is over that object is destroyed. Again it worked perfectly in 3.5.7. and I now resolved it but would like to know if it's anything changed in a way Unity4 handles yield. Thanks

How did you solve it if nothing has changed ?

I just adden new "middleearth" function that calls function with yield statement?
