This mutator or server actor adds proper holiday decoration to many maps. These decorations are not map-specific, but are applied to certain objects in the maps. In most cases, decorations are just visual additions, but in some cases they may change the way players interact with the map.
See the included text file for installation/usage instructions. If you use it as mutator on a server, the server will no longer be white-listed. But if you configure it as server actor, your server's white-listing status will not be affected.
