I was in the middle of the rank 30 archer quest and the game just stopped when i talked to an NPC named Pascaleret.

I didn't really need to talk to him, I just wanted to and when I tried he didn't respond back and then I couldn't really do anything else except move my camera and talk to my LS. I couldn't even open up the menu to log out.

So i ended up closing the game down and logging back in to finish off my mission.

Just some advise to anyone about to do that mission. DON'T TALK TO HIM!
