GFellows,
I checked again and winning a tournament doesn't crash the game anymore ; I don't receive anymore Bug Reports, so it's clearly fixed.
So what you state is likely something else : winning or losing, changing tournaments might make the game run out of memory. If I'm correct, then your game closes without any message, instead of crashing with the Bug Report popping up. Did I guess that right ?

If yes, then save the game after you have finished a tournament, terminate the game, launch it again, and you should be alright.
Also, very important : I got several reports about loading issue after have closed the game. I checked and it happened to me : the game tells me the loading just crashed. But actually, manually Loading the Slot Z works. So do that till I figure out what's going on exactly...

Bonus tip : save your game right after you have started a new career to avoid starting a new one if it crashes right away, and if you're a few weeks in, don't forget that you can load an automatically weekly save from World Tour -> Load Game.
