After speaking to the man with the 1806 code the screen freezes and you can't move or do anything.

Game has been mostly bug-free up until fixing the lighthouse. After that, crashed twice just getting from the lighthouse to the watchtower to collect the gun, crashed again shortly after retrieving the gun...then when I get to the boat that is now on fire, the conversation for the guy at the dock bugged out and the camera warped back to Gicu at the lighthouse. When the conversation was over I couldn't move and had to restart the game. When I got back to gicu, the same camera bug as the previous conversa...

Got the one at the watchtower, the "village", one in a building that looked like some kind of small barn or storage building, and can't find the last one. I've found a few other houses and a cave with a locked briefcase, but no fuse.
