If you have "RemoveBuildingForPlayer()" in your script and you delete it. After you recompile your mode (+ "GMX" ) and player doesn't leave (/q or "Exit Game") the game ,buildings wont show up for player. (Like "RemoveBuildingForPlayer()" is still in the script)

Once a building is removed from the player's game, it's gone until they relog(unless you create an identical object to take it's place).
