Building Forever

This is General/Graphic bug. I was building Mesh Tiles (because oxygen ran out) so I destroyed the floor and replaced it but then I noticed that two mesh tiles were weird and didn't connect to the rest of them in the white preview, so I thought maybe I should cancel these two because they still didn't build after every other mesh tile did but they wouldn't cancel, so I was like maybe if I build over it, it might work. So I built over them and it worked BUT when they were built they still had white outlines that I can't cancel and I even tried to destroy them and it finally worked so I mean still a bug but
