Odyssey Kayn Store

So, I was planning to buy Odyssey Kayn for myself on the 4 of October, except after I added the necessary RP and sorted the story to legendary. I couldn't find Kayn, so I assumed for some reason that he had rotated from the store. I have no clue as to why. Shortly afterwards I decided Project: Yi was a fitting replacement. I now realize sadly that was a mistake, but the point of this is to inform that Odyssey Kayn is not sorted with the Legendary skins which he needs to be a part of so others can avoid the mistake I foolishly made
