Straight stairs not working?

[Leivunit]

Hello, please excuse me if this is the wrong forum - if so, please kindly point me out to the right one.

I've searched around a lot, but alas, I haven't found anything much about this specific problem, or how to fix it.

For some time, whenever I try to place straight staircase, the tiles on the upper floor do not disappear and it gives me an error, even freezing the sims on the lot until I delete the staircase. The spiral staircases however work just fine.

Could anyone please tell me what to do with it?

Here is part of the error log (I hope it's the correct one, I'm sadly clueless about these things):

Thanks for help!
