Dynasty weapons.

Hello everyone.
Regarding the disappearing weapons of the dynasty. I found a way to keep them. As I understand it, the probability of them disappearing depends on the hero's specialization (mage or warrior), i.e., with the Kirin's Sword, if you play as Irina the mage, the sword will disappear in 80% of cases. Although, I didn't understand why the Feather disappeared with Anton, he's a warrior.
I read about this method in the game files in one of the missions, and it hasn't failed me yet. It was written by someone, I've already forgotten his nickname, but a huge thank you to you, man, I tried so many methods before.
So, enough rambling, here's the method:
Step 1: Just in case, save before receiving the weapon (in case the method doesn't work, but I haven't needed these saves anymore).
Step 2: Receive the weapon.
Step 3: Exit the mission to the main menu (where the guy with the sword stands), go to the dynasty, and check if the sword is there. If it is, great, load the save and continue playing (praise be!). If not, then continue.
Step 4: Go back to the campaign and start it again, but create a hero (before starting the map, below the main hero, there is a free slot, click it and create him, he will be the main one) with a specialization in the weapon (if it's a staff, then a mage, if it's a sword, then a warrior).
Step 5: Start the campaign, give the hero the weapon, and win one battle (you won't be allowed to lose! you can even win with auto-attack).
Step 6: Exit to the main menu, go to the dynasty, check the weapon, and voila! the sword is in the dynasty!!! Hooray!! We're awesome!!
Step 7: The weapon is there, load the old campaign, play, and enjoy until the next bug.

THIS DIDN'T HELP... WHAT SHOULD I DO... I WANT THE STAFF OF THUNDER... IT DOESN'T APPEAR
