I have stumbled upon several problems that might be bug related.
1) When I plan some tournament for a player and still enough in advance I deselect it (without information about cancellation fees) the player is charged some fairly large amount of money depending on the importance/total prize of the tournament.
I am not aware this should be happening (and not without confirmation), the amount appears next week as Taxes.
Just start the game, plan and cancel Indian Wells or similar and you have some 3,500 $ less :-/ (I've tried WTA)
2) I have noticed that when a player plays the same week regular tournament and quallies for the next, there may be incorrect results.
If the player loses in the regular tournament and wins the qualification for the next the same week, the game states him being a winner of the regular tournament in the statistics along with money and points.
I am not aware if the loss has to be some specific round or if the two tournaments have to be some specific combination.
I might be able to get you some savegame with this problem and then I can send it to you.
