Forum:BUG IN LITTLE LAMPLIGHT

Yeah. I entered litle lamplight by saving those 3 brats and now i cant enter vault 87. I got no dialogue options neither from the major nor from joseph. nothing. Also I can see the little square that is filled out when you did a quest at "Picking up the trail" at the point "get entrance to little lamplight" is not filled out, though i already got the garden of eden quest. Is there any cheat to get me entrance to vault 87? PLEASE I AM DEVASTATED
