Unlocked all hanzo mythic upgrades for only 50 prysms

Yes you heard right… I unlocked all 3 levels of the mythic hanzo skin even tho I only paid 50 mythic prisms. I went to skins to customise my Hanzo skin and that’s when I realised that I unlocked them all. 30 mythic prisms are still in the battle pass. I was wondering if I should keep the next 30 prism or if I should buy the next 2 levels even tho I already own them ( technically )

I also wanted to know if blizzard takes this stuff away next season or if this is just a visual bug. ( my teammates see the same skin as me )

I’d recommend against any upgrades in the mythic for this season. In case it’s not plenty obvious already, there are lots of bugs related to that and you won’t enjoy losing more mythic tokens if they bug out later.
