Unlocked Permament Illaoi Emote But Didn't Get It

So last night I opened up a chest and it was like the gold mine I'd always wanted. I ended up getting a gemstone and the Illaoi Emote unlocked permanently. But when I go to check my emotes and stuff it's not there, or in the shop at all. I researched on the forums that it was a limited time thing, but is there any way that I can get that emote since I actually did unlock it from the chest, or is there any way I can be compensated for the emote if for whatever reason you guys can't give that emote out? I'm a 500K mastery Illaoi and I was SUPER excited when it popped up but now I just feel kinda bummed because it's not there.
