I am at a loss on what to do with this quest, I have cleared every accessible cabin, obtained and read all 7 notes, killed every boneshredder, searched every square nano-meter of the island and there doesn't seem to be any sign of what happened to the 2 girls at all or how to enter the locked buildings or the door behind the barrier. Any help would be appreciated.
Ah thanks, it appears they don't appear until you get right to that spot, at least for me.
