When i'm playing solo Railjack and manning the top turret, loot has a tendency to fly behind directly me and is unable to be picked up. This presents two problems, as it not only blocks my view but even seems to actively block my shots from passing through.
Another bug was on a Corpus Defense section. I did 5 rounds of defense and then extracted, but the mission counted this as a failure. Afterwards the mission broke completely. All HUD elements outside of the Railjack disappeared and while i was able to board the Corpus flagship again, the Defense mission did not allow a second defense.
