Not sure if this is a feature or a bug?
I really like your addon as it makes reputation and questing easier- props to you all!
I'm using the auto turn-in and auto accept feature to turn in the ZG coin quests (though this would also apply to the thorium brotherhood and many others).
There are three separate sets of quest turn-ins on the same NPC. Unfortunately, after you complete your first set of coins, the second set does not get auto-accepted, instead it fails on the first turn-in, again.

Is there a workaround? Don't see to find it if there is. Perhaps I did not dig far enough.
