Why am i unable to place these inside of buildings anymore? It is the only way to protect but all i get now is overlapping issue, aint the wheel as theres plenty of spacing in the building to fir and i cannot even place 1 anymore 
How big is the the building and which wheel are you trying to place?
This is from October of last year. I have since removed the wheel and placed thralls and furnishings in the area for it’s original purpose.
The building is 8 x 9 x 8 in size (W,L,H). I have not tried placing a wheel in there since the last update. I detailed the build in my guide in the section on fixing a broken roof.
