Many, many thanks!
Updated LeanTween and i got an error:
Assets/LeanTween/LeanTweenExamples/Scripts/ExamplePunchJS.js(24,25): BCE0023: No appropriate version of 'LeanTween.rotate' for the argument list '(UnityEngine.GameObject, UnityEngine.Vector3, float, Object[])' was found.
but deleting the script solved it (hope i didnt break something else)!
Thanks man, have a great day!
