When creating a custom lobby and activating all 4 campaigns, even when locked to “allies/axis”, the game still seems to allow any allied faction/squad to be spawned on any map (e.g. Tunisia Italians in Moscow 1941).
While some players might enjoy the lighthearted approach, it would be great to also be able to experience all maps and game modes from all campaigns with default, historical factions only, without having to hop between different campaigns manually.
