Have you gotten this since? It might have been a hiccup from lag. I just tried to replicate it and couldn't.

If it hasn't happened again then I guess? I mean I cannot guarantee that it won't but it looks like a harmless lag error.

I am unfortunately not a programmer. I know it has been happening still on quickstock. I was just checking to see if it was still happening in the DC.

There is also already an open topic for quests so I am going to close this up.
