After reloading my save the HQ building bugged out, seemingly a new structure had been placed on top of the old one but rotated resulting in the window becoming closed and panels texture bugging out where it overlapped. I cleared the structure then removed it with the grinder to replace it and fix the issue, however it only removed one of these and parts of the frame from the original structure are stuck in place with the grinder not working to remove them.
Reloading the save after this also didn't change this so I'm either left with a floating structure that blocks me replacing it or with a bugged out building with the textures essentially flashing.
