[Bug] Billy won't spawn in Unfinished Bussiness quest "Kidnaping of Boo"

For some reason when i get to the docks diretrict he is not there, walked all around it, entended the inn in whose entrance he should be spawning on several times as well. I also tried using the console to spawn him but he automatically despawns. This has rendered the quest impossible to complete with Minsc being stuck at STR 10 because of it.
