So Im trying to make a sky high hookah lounge, bar, stage, and movie theater and I have the stage, bar, and hookah lounge complete. But for some reason when i try to place things down for the next room they refuse to go past a certain spot. Like they move and move and move then just stop. I had previously placed flooring down in the spots and the flooring that seems to be in the bugged zone refuses to move at all, like the controlls are completely frozen there. Is there any fix to this? Is it a known issue or is because im making everything 100 feet in the air?

There also seems to be a bug that when i copy and paste flooring it will paste it slightly below the existing one, and when i try to set it to the correct height using numbers itll force itself back down slightly under where it was. Completely weird bugs im getting.
