Known Issues:
- there is a bug if you equip the exact same weapon twice with the Sledgehammer, the second gun uses ammo from the magazine of the first gun, and will stop dealing damage when the magazine of the first gun has been emptied, it's best to use different guns in those slots.
- all players must use the same configuration of subkits
- you cannot use the Hunter kit and the Saboteur kit from the Saboteur mod at the same time, as they both modify the Gunner kit
