Possible mandella effect from early game

I first played Genshin sometime in late November 2020 and when the 1.2 update came, none of my devices' storage could hold the game, so I had to wait up until 2.4-2.7 to play again and I often found myself remembering the games' older rules that no longer applied, and remembering mechanics, which are no longer inplemented in the game, for example, that the chars the player sends out on an expedition can no longer be used in combat, the bow charge attack cursor looking different etc.

However, there's still one that hasn't proven to ever be in the game and I'm curious as to if any people who, also had either a gap in their time playing or just remember it the same way, can relate.

What I remember being in the game (circa 1.1) is a very specific passive talent or ability or a gameplay tip of sort about mining ores in the overworld. Specifically, that either one specific character or any claymore-type character has a chance of obtaining/dropping more ores when mining. I also can't really connect what this mandella effect could even come out of in the first place, since anything that even comes close to this kind of ability is in the chasm, which came way later.

I don't have much experience writing posts like these, but I've been thinking about this for a while and wanted a possible opinion from someone else who might remember more than I do.
