While Buddy is great in single player, ive been playing with one other friend lately and Buddy is kind of the worst lol. A lot of the time, we will be crafting ammo or a repair core and right after crafting said thing Buddy makes and installs another one... There should be an option in the hanger to tell him to not join.
Or adding a feature to tell him which tasks to do and which tasks to not do on the ship could be really useful.
