PSA: Cube 3-1 rerolling three NATURAL mythics gives CRAFTED mythic back

So i got my 4th mythic ramaldni drop. I decided to reroll the 3 (naturally dropped) ones i had in stash hoping for better stats than one i had equipped.

However it seems that 3-1 rerolling three NATURAL mythics still gives back a CRAFTED mythic that can no longer be equipped.

So yeah. You cant even 3-1 them lmao.
