as I already said : multiple return stances = invalid saved games, so not before I actually have to do some other changes that would also invalid the saved games.
Raz,
nothing changed in the gameplay except the things listed in the Changelog.
Sabina Lisicki,
if you bought the game, then you'd not mind.
And you still can play for free, so that's not that bad...

Algo,
- Modded game issue, I guess.
- Mishits were not changed and they always had a chance to land on the line (depending of preparation time, etc...).
The Potro & Forzzzz,
about Desync, you should assure that both of you and your opponent have the original unmodded game, and possibly the latest demo, not the patch.
