I noticed that even though our team won, a loss was calculated and Crucible marks and XP was "rewarded".
I had 3 medallions from the last IB tournament and lost the first match from this week.
I bought a buff, had equiped my "Jolder's Iron Sash", shader and emblem.
The second match on Saturday March 21st 2015, our team won. So I expected to receive a win, 4 times medallion rewards and 40% "bonus" points. My level 32 Titan however still has Rank 0 with 0 rank points.
Instead my medallions were lost and 2 lost games were calculated anyway.
Addition: (About half an hour later):
This time a match was lost again, but nothing at all was rewarded. No Mediallion, no Crucible marks nor Crucible XP. Nothing, totally nothing.
Additionally I noticed during the matches that level 29 players, with not fully upgraded weapons were able to kill me instandly, without me doing little to no damage to them.
I really would urge Bungie to fix your network connections. The already poor quality of the network connectivity to Bungie servers/services gets even worse on Thursday evenings, when updates are deployed, related to Xûr.
Issues like these start to annoy me!
