Firstly Cartographer mod requires Network tab,
therby u cant play on Lan using the mod even if u are offline
If u want to play in Lan then remove or rename xlive.dll in your Halo 2 root to disable the mod
Then That should enable Live services and create an offline Live account
Now connect all...
I belive this is a issue with some servers caching the user data
The only fix i have found is to reset ur Internet connection to refresh ur IP
Like if u run on mobile data then just restart ur handset or etc to get a new dynamic ip
Also for anyone wondering about Tag Indices or Datum Index
Look into Assembly - The Blam Cache Research tool (ofc :p )
Open up a map (say shared.map)and select any tag , The Information Tab lists the required DatumIndex
Yea some experimental tests resulted in working of new levels
Like Teddy hosting Gravemind or Metropolis and Cairo station
But even that method is pretty much bugged and chances are still to work
Moreover its entirely a hack wacky method which idk but somehow work
Thats why i wanna tell people...
Currently Project cartographer doesnt support lan mod
So u can either Disable Cartographer and play orignal halo 2
