I've accepted alot of quests around the lvl 27 - 29 area. I open my quests (J) and i have them all activated and i have to kill 20 of something but i look on my map and nothing is there. I look in every map and there are no red circles. I try to get into the dungeon (UD1 next to the main village on the second map) and for some reason I cannot go inside. Where are my quests at and why can't i get inside??

Your quests will most likely be in UD1 or the RP dungeon. UD1 you can only enter in a party.

Heh. Times like this it pays off to have friends.
