Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? Yes
Please describe the patch or change you made. it happend with the latest patch
When you are on the second floor and you hover the mouse over the ground floor sealing it apears and dissapears. Even when the sealing was build
From what I can see in your pics, it appears that you have deleted the ceilings or the floors above them. The grid should be showing just like in the other spaces I can see in the pics so it looks like the game sees no ceiling there. So I suggest you select one of the rooms that are open, hop up a level and click on the yellow border around that room to see what options you have. If you have Build Ceiling, then click to build a ceiling. If you have Remove Ceiling, then click to remove it and then click it again to build a ceiling back.
Hope this helps.
