I'll admit this is a relatively dumb question, but rules wise, I do not think it is covered, so...
SF23 Iwabuchi's Sarcophagus uses an SSR to turn the Agriculture Building (printed Level 2 with 2 staircases) into a L1 with no cellars per SSR 2: "Neither Level 2 nor SF Cellar Locations (SF4.4) exist in Building 2Y52, but stairwells still do."
Now normally this building has a rooftop per SF4.3 as a Stone building with a printed stairwell, which per that SSR it still is. So...Does 2Y52 still have rooftop locations? If so, what level are they? Level 2.5 like normal for that building? [In which case they probably are not accessible since L2 doesn't exist which makes it a relatively moot point] Or Level 1.5 since L2 locations do not exist?
Reading the Prelude/Aftermath, it sounds like the building was bombed out and crumbling which is likely why L2 and Cellars do not exist (and it may be a scenario balance thing as part of the VC is taking locations), so it likely does not make sense that rooftops are in play, but there is of course no rule saying rooftops are not in play just because Level 2 was SSR'd away.
Thanks for any thoughts...
