Hi, (probably not so much a bug as a feature not implemented?)
When I design an historical mission (Historical Units button on) in the ME it doesn't stop players from choosing non-historical weapons when in game.
Example:
Historical units button on, mission set for 2008 therefore, SIDEARMS for the Harrier not available to select in loadout (phased out in 1990) - correct.
However, Client in-game and can select them to load via the Ground Crew menu.
How dare he use old tech! LOL!
I know, its not a biggie, thanks for reading.
