Skin shard disappeared

So i just bought 10 true damage orbs. Opened them and was lucky to get a true damage yasuo skin shard. I rerolled the others i didn't like. I go back and check my loot later on and the true damage yasuo skin shard disappeared. I know i didn't reroll as i was excited to have received it in the first place. Has anyone had this issue with true damage skin shards or skin shards in general? and did riot fix this?
