I'm not sure when this changed, but I swear walls used to be flush with the roof-created walls, but lately I'm just seeing that tiny misalignment and it's driving me crazy lol, I can't use roof walls without using some kind of trim to hide the misaligned gap.
Happens in vanilla
the grey line that separates the roof from the actual room :(
it also causes serious misalignment for vertically-striped designs!
