Hello.
I maybe I found a bug (?). If I play a match in world tour and give up - continue later, and then do the same thing in a match training, when then return to play the match in the world tour, it gives me the same score of the match training! The same thing happens when then I play again the match of training, the same score of the match of the world tour. Sometimes I over to give up - continue later, I also save the current game. But when it happens this bug (?), loading the game does not work, in fact if I try to load it always gives me the same score of the match training.
The only way to solve the problem is to eliminate the current game of the match of training, and then start another game, give up and choose yes. Once this is done, I go back into the world tour and I can load the saved game (which now works) and continue playing from the point where I had given up.
I use Tennis Elbow 2013 v1.0a, no mods, and my system is Ubuntu Linux 12.04 64-bit.
