Bringing both points here to bring something up.
If FNAF was being designed for Soundstage 15 in mind for HHN last year; and when things happened and Weeknd took it's place--then that still means FNAF was being designed and/written for that venue in the beginning.
While ordinarily some would appropriately say "so what"; I would like to bring up that for the past two Puppet/Tech houses, neither of them have needed to have that of a advanced cooling system into place. It also doesn't exactly make sense in terms of the scenario that FNAF would need to be a tent house that'd require AC.
I think if we're looking at options, FNAF is in SS15; Fallout (if it's happening) is in UBE, and whatever is in this house at H-Lot North is being made to be cold in mind. tbh if it wasn't for the slate looking like it was, I'd almost wonder if it could be Nosferatu.
