In a game of Warlords, you aren't able to put on UAV bags or mortar tubes for balance reasons. Even if I load a pre-made loadout with a mortar tube or other illegal item, I'm unable to put it on my character.
However, in custom missions, you're still able to load loadouts that have items not shown in the arsenal or otherwise not meant to be used.
Is there a way I can implement the same loadout restriction from Warlords into my own custom mission? Or is this just a quirk from an official gamemode like the Warlords buy menu (which I would also like to see if there is a way I can add that to my missions 👀)?
