Inside the part_trader_tile_filler_01.2532 POI there is a piece of trash which has an invisible column above it which is occupied by something I cannot see or break but blocks construction. I am not great with the debug menus but I fumbled my way through what I know and made a video demonstrating the issue on two maps inside the same POI. Please see the link below.
I should add I did follow the recommendation of disabling anti-cheat and validating the local game files before testing and recording the video.
