2 games in 1 bug

I was spectating The Tactician dueling EndsOfInvention and then i joined a 3v3 it said The Tactician and EndsOfInvention were playing in my game.
and i picked italy then EndsOfInvention had milan on turn1 and all cities looked weird
then i could see both chats http://gyazo.com/ebaca73a431e1e7840e32c3d9dda1178

here is 1 more screenshot http://gyazo.com/1b3a77682a86b3c3a8126aaef0fced26

He was in my game, my 3vs3, I saw, just so no one thinks he's crazy lol. He was actually in my game and I started seeing what Tact and Ends were saying as well, altho not sure if they finished their duel and were actually spectating or some weird shit was going on. I also stopped hearing people from the game I was in and only saw Tact and Ends speaking, although it could of been people in my game being quiet I don't know.
