Whats going on with this Archway placement?

So you have not built anything except these rooms... No platforms, no walls, no rooms, no stairs, no roofs? Have you tried it on a different plot? Also, never used any mods i'm guessing, cause pretty sure even MOO would let you place those archways anyway :p I just saw @metaphasic placed the archways where you could too, not where you wanted them, I'll see what happens for me in a bit;)

edit:
I have no clue man, no issues here :'(

Actually, I believe his example picture was showing the ONLY place he could place them. Unless I misunderstood, he was saying that if he moved it closer to either wall, he’d get an intersection error. I could be wrong though.
