scarlet dagger
So the R.A.M. messed up and destroyed the whole map, but it could reconstruct the map. (literally what it does, puts things together) Since we were put in a simulation to make it feel normal, what if the people working on the R.A.M. fixed the machine, put the map back together, and we got brought back.
Im suggesting this because a lot of people want the old lobby back and this is a way to bring it back without ruining the lore.
