stairs wont work properly with the new platforms. a black square appears on the floor. I've mainly experienced this at basement level. 

I've also experienced problems with the stairs in a way that they jump to the platform level next to it instead of the one its connect to... 

platforms and roofs are not working great together either. the roof dosent consider a normalwall a wall if its connected to a halfwall. like [_] can be normal. but if X is a platform and the 4th wall is a halfwall the roof will just cut straigt through.  

platforms in basements and attics dont seem to work.

@saralisa55 I clicked a Me Too for the "I've also experienced problems with the stairs in a way that they jump to the platform level next to it instead of the one its connect to... " A moderator's opinion was it's working as designed so my post is in the general feedback section, but in my opinion that design feature is so unintuitive and annoying it jolly well should be counted as a bug!!

I have the same problem with the stairs and the platforms with the black box under the stairs. My sims also get stuck on the platform, they walk up the stairs but cant go back down them. The roof coming through the wall has always been a problem it also happens when you split a room with a fence its because you have two different rooms without a full wall in-between that has always been a glitch.
