NO MODS - VANILLA 41.72 - TESTED SP ONLY, MAYBE MP HAPPENS TOO

 

If you try to build a wall where an existing building has a corner pillar, and then create a room out of it, it will not be classed as indoors due to this existing corner pillar. If you remove it, the indoors classification is applied. See below images and notice the isoRegion debug showing as empty/coloured.
