Large buildings have one registration hex. Usually the upper left portion but not always. I have seen them go away when making a map when something is placed though the registration hex but I cannot recal a hit that removed a the whole building

Was it tucked right into the top left hex of the map ?

In any event, It would seem that would be a separte issue to the rogue junk terrain issue..... BUT, if you look at the first image in post #113 there is enough junk there that could hide a building IF enough of it was on the map.... maybe

Do you still have this save game?

ANY saves that show the terrain junk on the left edge that anyone has I am interested in so I can run them with both the release EXE and the fix EXE to see if the fix removes it and if the game continues it stays removed. SO FAR any of the scenarios that have crash reports about them and edge junk that I have ran have all ran to completion with no return of edge junk
