I would expect that any quantity of tweens started from the same "frame" would be always syncronized. But since SimpleActuator set the "startTime" var with:
Lib.getTimer()
every time a new tween is instantiated, each instance gets a slightly different time and thus get desynchronized from the others.
As a fix suggestion, maybe instead of lazily listening to Event.ENTER_FRAME, listen to it before any tweens are instantiated and keep a single value from Lib.getTimer() as startTime.
117 I've created a PR to fix this. Hope it helps. I think the PR version is better since, it guarantees that for all actuators instantiated in the same frame, they all get the same startTime, as already happens with "stage_onEnterFrame" that is called only once per frame and calls update on every actuators with the same "currentTime" instead of fetching a new Lib.getTimer() for each one.
