I'm trying to build and the floor won't appear when i make a room. Cant place flooring either. Doesnt work with platforms either. I tried repairing the game but it's the same. Anyone else?
Can you please sharing a screenshot(s) of the issue? Thanks!

I look forward to hearing if you have any results from any of this to know if we should pursue other options.
