i had already removed those buildings using CA_RemoveBuilding before initializing using CA_Init under OnGameModeInit...
however, when i call the command gmx the whole server gonna crazy and gets full of ERROR: CA_RemoveBuilding : Map has already been initialized. Use this before CA_Init. errors...
as i am removing buildings again from the Database after Server restart so ColAndreas is already initialized and the Buildings is already removed... which is annoying
