i can not seam to place stairs to second floor (its actualy metal half ramp) in correct position inside building, it either refuse to snap in correct direction or snap at all and unless i remove several tiles on bottom floor, then i can not place tiles back couse they do not snap in thus leaving hole in bottom floor of base

i gave up on placing half ramp inside and placed (full) ramp instead

Yeah, me too. It's a bummer. I'm not a big fan of the newer buiding parts.

Same here. Half stairs are useless now.
