For anyone trying to connect to the TC_DaVanichta_V8 map, and having issues:
Due to issues out of scope of this text, any prior map has to be deleted before trying to connect:
Go to the <install path>\Mods\MWLL\Game\Levels\Multiplayer\TC\ folder.
locate the TC_DaVanichta_V1 folder and delete it (Yes the folder is always the *_V1, no matter which version)
Start the game and try connect (and allow the new map to download)
