when you crash, which is an average of 4-5 times per mission for my case(actual number, I recorded 10 games across several days and counted) if you have a grim, ammo/heath case, grenades, ammo, health or really any resource. by the time you get back into the mission the bots find a way to use up every thing you have
I genuinely think that they just set it so anything the bot is holding it uses automatically because they cant process the bots invintory
