NPC desync issue (Assassin's Creed: Valhalla)

Naturally, kill two civilians, wait plus or minus a minute, and kill two civilians again)
But seriously, you should have known very well that it would be impossible to kill residents with impunity if you played at least 2 other parts of the AC.
My advice, if you want to kill, look for mods, but I'm afraid there are none.
Yes, and the "Vikings" did not kill everyone in a row, but they even loved the slave trade, but in a tolerant Ubisoft they will not implement this.
