So I was on my way to the beach to regroup with the others and noticed a box in shanty that I forgot. I went down and got it then did the tomb and collected everything I could. For a while I thought I was stuck down there till I finally found a way out using fast travel to a different area of shanty town. When I got back to where the lift should be to go down the mountain side there seemed to no longer be one. Dx I'm not sure what to do.. I kinda don't want to revert to a previous save but I also don't want to be stuck forever =[
