Skins Changing?

Basically, I've noticed that my skins that I normally have selected aren't auto-selected anymore. For example, Nami: sometimes it'll have River Spirit Nami selected. I usually have Koi Nami selected, but the game is automatically trying to choose which skin I use. The reason I use Koi over River Spirit is that I have the Chroma. Sometimes the game does have Koi selected, but then it'll take off my chroma, again independently of any choice made on my part. And Nami is by far not the only champion the game does this on. It's a new problem, never happened before; just recently. Do not appreciate thinking I have chroma on and then getting in a game to find out: no, in fact, the chroma isn't on. Why bother buying it if LoL is going to turn it off? [zombie-brand-mindblown]
