Describe the bug
If a quest is turned in and a new quest becomes available, the QuestFrame often remains hidden and can't be interacted with anymore.
The new quest also isn't accepted.

How to reproduce
It doesn't always happen, but it usually happens if you turn in a quest and another becomes available after.

Workaround
You have to move away from the npc until you hear the QuestFrame closing (even if it is hidden) then talk to npc again.

Let me know if I should test something, I get this almost every time. Might be because the zones are kinda laggy right now (at least on EU).

I've noticed this too, kinda hard to reproduce consistently, but I'm looking into it.

Can't reproduce this any more, guess it was just lag during the launch.
