BHG missions, Omega 15, Rostock station, several times.
Missions of the type "capture person and bring pod back to base"
When I am flying alone, I kill NPCs, collect the mission cargo, and return to base, no problem. But after docking, the message "mission failed, group lives exhausted" shows up. Rep dropped, no money added. Sometimes the mission cargo vanishes from my hold, sometimes it stays there.
Happening quite often to me now.
In Freelancer Discovery, you can be anyone you want. It's strange that so many people choose to be douchebags.
