Hey Manutoo,
Found another bug which is really quite annoying. I've found that my player for whatever reason the racket keeps changing position in his hand and as a result sometimes I've found both the forehand animation and the backhand animation to be really off. As well I find that that actually slice with the racket facing downwards. I wouldn't raise this if it wasn't actually affecting the game, but it absolutely seems to be that when the racket is out of position or looking really off it affects the aim of the ball completely.
Worst case that I can produce this on is being a lefty with a Murray animation back hand, the frame of the racket is completely crossed rather than the strings being flat and visible when going to hit the shot. It seems ok in training club but with my world tour character it seems completely off. I'll try and see if I can capture screenshots.
