May have discovered game-breaking bug in the Pyramid.
So my team is Adventurer, Scientist, Time-Traveler, and I'm in the Adventurer's area (the Pyramid). I went up and unlocked the lower area containing the four switches (Snake, Crane, Jackal, Lion). I moved the Adventurer and the Time-Traveler into that room, and the entrace shut behind the second one, leaving the Scientist the only one outside the switch room. The problem, is that all of the other areas accessible in the pyramid at this time, including the areas that seem to be opened by the switches, require the Adventurer to traverse (spke pits with grappling hook points). It's possible there's something I'm just missing, but it seems like I was meant to leave the Adventurer out of the switch room.
