As i've posted a few times my game freezes when i get close to Novac so i decided to explore other places until a patch comes out but after about 6 hours of exploring i ended up on the Vegas Strip and after about an hour there i have about 4 new quests that seem to be the same quest just with different ways to complete and i hav'nt a clue of where to go or what to do.

I got a note from some NCR dude to meet with someone then got a similar note to meet some Legion person, i have a quest to go to some bunker, another to meet with the casino owners and the BOS, then another to kill or disable House, but i had to skip whatever happened bewteen Novac to the Strip.

Was there anything important bewteen Novac and the Strip that'll help me choose what to do?
