My scaling sword does not scale up

[kordinate]

Hi.
I'm playing wichter3 and have some issues with my "scaling swords".
My aerondight, winter swords doesn't level up when my character level gets up.

Note that I didn't put the swords in my stock box, but I carried them and equipped them throughout the game.
However, I found the sword doesn't level up when Gerault level goes up, especially when main quest is completed so a lot of xp has gained.

Some say that the level notation is not correct and damages goes up anyway, but I found the damage of the sword also doesn't scale up.

I searched google to find someone having the same issue, but couldn't find one.
So I make this thread to find someone who has the same issue, and to figure out whether this is a known bug or not.

Thanks.

At least on Xbox, those swords never seem to level up all the time, but just most of the time when I level up. But Aerondight in particular will never get stronger simple because Geralt is stronger. You need to use it and kill monsters with 10+ attacks, without getting hit, for the sword to level up.

Aerondight doesn't scale up its damage based on your level. Its damage scales up based on your attacks. Here's a scenario to explain. You have Aerondight, and you get into a fight against some drowners. You attack twice and both attacks hit. Starting with that second attack, you have a combat multiplier that increases every time you hit with an attack, without taking damage yourself. If that multiplier hits 10, there's a chance your next attack will insta-kill your enemy. If that happens, Aerondight's damage will increase. If you get hit, the multiplier goes down; if you win the fight before the insta-kill attack happens, you have to start over.
