[Golist] SkipTo question

[James Bligh]

Yeah that would fix it, thanks for that. especially the speed.

While I'm pointing out flaws, (I hope this is helpful)
In PlayableGroup.as line 408
    position = _repeater.skipTo(_repeater.cycles, position); // TODO: TEST

The repeater skipTo method takes the tween duration or sequence length as
it's first param
Passing in repeater.cycles doesn't seem to make sense in this case.

In my case I don't have repeats so repeater.cycles will be 1 and
repeater.skipTo will set position to 1!
So I've commented out this line as a work around.
So it's tested for that use case if that helps

At a guess I'd say you want to actually pass in _repeater.cycles *
durationOfGroup
but there is no method or var that represents the groups total duration.
