Skin shard re-roll bug

So today I opened a chest and got a skin shard for a champ that I really didn't like. I had 3 of them so I decided to re-roll them into a random champion skin shard. During the re-roll animation my PC crashed that isn't that surprising and when I logged in League later I lost all 3 of my skin shards and didn't get anything back. That just ain't fair. Please RIOT do something.<3
