So after pulling the levers in the order I suspected as being required, it spawned an encounter in one room and opened a hatch down to another level. When I went down the hatch, the room itself was very weird, almost like a placeholder room, and there was an arch with something like a force field preventing me from going any further. Did anyone else get that? I'm wondering because I have had glitches trying to leave other areas like the black cove, that dump me into bizarre unfinished areas outside of the alpha zone.
