I just wanted to report something that seems like a bug. I can not add any games to R2P. After using "Add more games" on a game (in games explorer), the label "ready to play X games" still lists the same number as before, and clicking on it does not list the newly added game, the same goes for the "create invite" GUI. However, when I click "Add more games" again, the game is listed in the popup window. Now, when I add a game that is not auto found by R2P using the Browse button, the game is also not added to the "ready to play X games" and the invite gui, but clicking "Add more games" also does not list this new game. I think this is the problem: I currently only have games in my list that I bought on Impulse, other games just do not show up.
Restarting Ready to Play does not solve the problem. Reinstalling Ready to Play also does not solve the problem.
