I have one base built on a planet, with my Freighter dialed in right above, planet side. Each time my Base Computer Archives finishes the timer for unlocking new things, the marker to achieve the mission is placed on my Freighter. The actual Base Computer on the planet, does not function as expected, only showing base removal, upload, and rename. This is because the marker is placed elsewhere, my freighter.
Only way to solve this is by having the mission selected (P > Logs), then save and reload. Only then will the marker actually appear at the Base Computer on the planet again to collect reward.
Note: Currently these rewards appear to be looping, giving me a Life Support Upgrade (B) every single time. Started storing them, even though they do not stack.
