Monthly Challenge

I’m not sure if this is a known problem, nor is it really a big one. I finished the monthly challenge last night only to receive no experience. The reason for this was because I was SR 49 with about 800 xp away from leveling. When I finished the last game for the challenge, I only got the xp from that game. When you reach SR 50 it stops your xp from continuing until you choose a specialization. I wanted to point this out because there might be others like me who are frustrated that they played 117 games and got nothing for it.
