As last picture shows, it is not working the way it should. As there is no difference between 3rd and 4th pic, except of one corrupted square, where I can not build foundation, even if I should be able to.
You can see corrupted square at 2nd pic.
There ARE foundation squares on lower level, but game tells me ‘structure position is not valid’
Hmm, can you send this specific case in via the bug tool? I think we need to look at it to see what’s blocking the placement. My assumption is that there’s something with the top part of the foundation you’re dragging that being blocked by something.
Nevertheless I can not load the two latest saves of this airport. Loading screen was stuck at ‘loading game data’ for >90 minutes.
Tried both saves two times, so 6 hours of waiting, in total…
Could you please tell me, if you can load that save?
Hmm, try using the bulldozer in that area on floor 2. Maybe some object is left that is blocking the construction. Regardless we will look into it later.
