so i was screwing around in vault 112 after i finished tranquility lane, and after using tcl and travelling (eventually) west of the main pod room i found an empty box and a hatch leading to the tranquility lane simulation (it's far away, if you keep walking west you should eventually see it). when i entered i found myself back in the retro black/white neighborhood. i tried talking to the chinese soldiers and betty, but nothing happened when the dialogue initiated, so naturally i loaded an earlier save and eventually got back to 112 and tried to use the hatch before i started the quest. this time, i was able to interact normally with the residents and even started the quest line, but as expected after a while my game crashed.

so i was just wondering, because i haven't heard of this happening if anyone else has discovered this, and what your experience with it has been (were you able to actually complete the questline, for example?)

also, just now added an entry to the fallout wiki with a more detailed description
