As stated in the conversion kit rules, each room are now either indoor or outdoor. They give a list of what type each room are and except for the Rooftop that could have been either, all of them fall naturally in their respective categories. Except for Spruce Grove that really feel outdoor but is said to be indoor. Is it a mistake or will it be used in a way that really makes it feel indoor. I don't know yet the implication of a room being indoor or outdoor but Spruce Grove being indoor puzzled me and did not felt intuitive at all.

Some app effects target investigators in outdoor spaces, for example.

For rules inconsistencies, ask the question directly to FFG. They are really attentive these days to this particular game, it shouldn't take too long to have an answer

Did they answer if the Spruce Grove and Rooftop were supposed to be indoors as printed or is this an accidental error. I assume these are errors and are meant to be outdoors.

I actually just picked up the Suppressed Memories tile pack, and the tiles are all reprinted to match 2E standards, meaning there are no "line of sight" dots and the tile labels have the newer borders. Going through them, both Rooftop and Spruce Grove have the blueish "Outdoor" borders, so I believe that the conversion kit instructions are a misprint.

The difference is with the name... if the name of the room/area (not necessarily tile, for example the rental shack on the dock) is yellow, its indoor, if white, its outdoors.

BTW, answered in the FAQ just released.
