It's well known that the forward "FM_GetGameDescription" seems to cause problems/crashes. Well, with Orpheu not anymore. A *very* quick and tiny plugin.
Put these two CVars into your amxx.cfg / server.cfg or however you usually do it.
You must have this module installed
amxx_game_name "" - This is the original name of the game (This auto-detects if it's blank, RECOMMENDED to set anyways.
amxx_game_newname "My Game" - The name that the game should be set too.
You must put in "GameName.ini" into your "configs/orpheu/memory" folder.
