“Two Seasons: Summer-Autumn 2016” Tournament. Online games for rating (reports, discussions).

We also had a funny thing: the game would initially have password-protected saves, meaning that for the first 123 turns, the game would use password-protected saves, and then the passwords would disappear.

If the person uploading the game has removed (perhaps accidentally) the "Password-protected saves" checkbox, then all subsequent saves will be without passwords. Moreover, the removed checkbox will also be passed on to their opponent, and until they specifically put it back or connect as a client to a server where it is enabled, the games they start or load will also be without passwords. It is important to pay attention to this and make sure that the checkbox is checked.
