Something very strange just happened to me, I'll try to describe it the best I can:
I opened the client. I see that one of my friends is spectating a game so I click the "join" button. Later I leave the table but the game is still going on. I went back to the main screen and clicked the button that sets me up with a quick game against one bot.
That game loads, I play out the game, the game ends and I click the "OK" button on the window that says that the game has ended. It takes me to a game end screen, but it appears to be the game end screen for the game I was spectating -- not the one against the bot I had just played.
The table appears to still be right: I'm sitting with Lord Rattington at a table and I can edit that table just fine, but the results, score, deck contents and break down is all for the game I was spectating.
I'm not sure what other information I can provide but this was very weird.
