Title says it.
Details:
I have an "automatic unit launcher" in my power armor mk2, along with a personal roboport mark2. I have destroyer items in my inventory (~20). When there are enemies nearby destroyer's do get launched. However, each launched destroyer from inventory seems to only correspond to a single destroyer drone out in the world, whereas if I launched them manually each inventory destroyer would launch 5 destroyer drones out in the world.
I would expect that 5 destroyer drones be launched for each item in my inventory. I'm not sure if this is expected behaviour or not though.
