I am not sure what exactly is going on. But when I complete the mission and I get the box that says congratulations be sure to pick up your reward above the starbase. There is none to be had. Either they are being picked off by "team mates" or I simply am not getting my reward. for this kind of event, if successful we should get a reward, not have an odd man out situation. Do not like feeling like I am being shafted.
The entire group of players on the map should be receiving a reward each, at the end of the mission.
There have been some incidents where this was not happening, and the root of the problem was discovered and a fix was made. That fix will make it into the game this week. Hopefully, that will be the last of us seeing that mishap. If not, we'll have to wait for the next patch.
Those rewards cannot be taken by team members, though, btw. They should & shall (when not now) drop for you alone to pickup, just like your teammates.
