Hosts game is different to yours?

[Asanius]

I dont understand why most multiplayer games say this and i cant join??? Is there a specific mod most people download with the game??

if you got 1212 AD enabled you won't be able to play with ppl that play the vanilla version of ATILLA .

Also, even if you both have the same version of 1212 ad , you need to make sure that there are either no other mods enabled, or the exact same mods for everyone involved.
