Hello,   i wanted to upgrade from the old 2.x to the latest 3.x GSAP. Mostly everything is working, except the code below. I need to update variables during the animation without changing or resetting the duration—it should just continue to the new path like nothing happened.    In 2.x it was working perfectly, now im messing around with "quickTo()", "invalidate()", trying to get the old "duration()" and inserting it in the updated tween, but nothing works like in 2.x.
