Could you let me know which quests are giving you trouble so I can take a look? Things are pretty hectic right now, but I'll be sure to stuff it into the QA team inbox.
I would be forever in your debt if you could forward this issue to the appropriate people for me. One of my guildies crashed during that same quest, and now he cannot complete it either. Thank god for daily resets in the mean time

Edit: all in all though, I must say, I love the new map, the quests were fun, challenging (but not too challenging), and worth a good amount of XP. Also, thank you for double tp XD
