I've done 5 wanted missions today with someone however he lagged out a few times so I retreated a few times i.e. not completed the mission. The bug is that we both have completed 5 wanted missions today as we cannot accept anymore but in the weekly training it only has it marked down as 4/5 wanted completed missions. I think this is a bug, I'm not sure what else it could be.
aaa okay I see. After he dc'd he didn't have a mission so I abandoned and got it again so he could join me. Thnx. However the retreat doesn't count as a loss, done it a bunch of times before.
As aforementioned by other players, if you abandoned a mission, it will result in what you described. If that's not the case, please let me know, I will forward it to be looked into :)
