Okay, here's what happened: Queued for league. After waiting about a minute, I decided to check the Co-op chat to see if anyone has found the fairy yet. Clicking the "Co-op" button didn't do anything. So I clicked the league arena to stop the queue. Clicked "Co-op" again, still didn't open the chat. Clicked "Campaign", screen changed to world map with the connection lost message. Logged in. (I might have selected MP here, not sure.) Was told I was currently in a game, said yes to rejoin. Played my league game, opponent resigned on round two. Got the victory screen, and results screen. Clicking okay took me back to campaign map. No chest. MP ladder shows first chest open (I haven't played any other MP games in more than 20 hours). League results shows my win. Equipment excess calculator only shows only one excess item, which would be really surprising and unusual. (Not only am I close to max usable on most commons and uncommons, but MP chests usually have 1 or more treasures and there's only one of those I'm missing.)
Okay...... Just logged in again to check league progress (overtime, I'm still 2nd). Got the landing screen, but without the buttons for campaign or MP. Nothing happened for a while (tried to drag the screen but couldn't). Then it went directly to the loot screen with a gold chest. Chest contained CURR(E) from all levels (one non-excess). I guess you can call this solved now.
