... Is it possible to fix the removal of protection from a password-protected map?

Initially, I thought it might be due to this

3.45 -> 3.46 (10.06.2013)...
[+] Significantly enhanced protection of password-protected saves and maps
- - ATTENTION! Due to this, protected saves from previous HD versions will not be able to be continued in this...

But after successfully removing the protection (as indicated in the interface), the map loads and crashes. Naturally, the protection was not removed from the saves either. This is the crash in this situation.
By the way, there were 2 more crash logs, but they were overwritten by subsequent ones. The first crash occurred immediately when an opponent attacked my city with a hero and quick battles enabled. After disabling quick battles, the crash no longer occurred. And the second one also occurred during an attack on someone.
Sometimes, at the very beginning, almost immediately after generation, the game closes – you barely have time to save. Also, it seems that the opponent's password is not read or used during the first generation, since the loading occurs instantly without the usual delays.
And finally, a fresh AI bug. It is not possible to check whether this is due to a mod or SoD. The point is this: the opponent's hero, a Miner (level 1) with shackles, attacked my Moner (expert tactics) on a Phoenix. During the attack, a disconnect occurred. I did not see the attack displayed, and the opponent immediately saw a message upon entering the battle about the opponent leaving and was offered to save the game. After loading this save, I saw my Moner in the tavern with a pixie. That is, the shackles do not work for the AI.
