It often happens that the auto turn in / auto accept features for quest break the quest dialog. One quest gets turned in but than the dialog break and I have to cancel and retalk to the quest npc

This seems to be an issue with most auto turn in addons and from what i can tell is caused by server lag and the game not updating as quickly as the server registers that you finished the quest.

I was able to resolve it in testing with a delay but for how often it breaks and how annoying the delay is this will have to go 'unfixed' until a better solution presents it's self.
