Hello.
I've noticed a bug when you try to do the final part in the tirion questline. If someone turns in Scarlet Subterfuge he will start killing the scarlet mobs around him and then somewhat reset. If someone else turns in the quest when he reset he will be stuck in place... forever... or well, til you get ahold of a GM that can .kill him. Just thinking this bug should be addressed either by making him able to continue walking when quest is accepted twice OR by making it impossible to turn in the quest when he's already started it.
Thank you for your time.
