I've noticed a bug that happens when you reload a save multiple times in your player character's 'Activity' page (the page where you see his prize money and tournament results). Basically, if you keep reloading a save file, it messes up the player's tournament history and ranking points. I think this only happens with your player character and not the AI profiles, but it can screw with the player character's ranking as tournament entries end up being duplicated multiple times or missing (I'll attach images below, but in my example my ranking had both jumped and dropped several hundred spots because of the glitch). This is fixed when restarting the game and reloading again for the first time, so I don't think it is permanently damaging the saves aside from anything that happens with your recorded rank and allowing/preventing you to qualify for tournaments that you shouldn't/should be able to, but I think it happens every time I load a save file with 100% reproducibility.
Steps to reproduce:
1. Make a character
2. Play several tournaments for a few weeks in a row
3. Reload any save file multiple times in a row
Reloading after immediately starting game:
After a few reloads (some entries are missing):
After a few more reloads (many entries are duplicated and wrong):
After one more reload:
Sorry for not attaching save file as I used a friend's name as a joke and would rather not reveal that. Thanks!
