[Client 7.4] Bug chest and keys

Hello.

I had 6 key shards and 5 chest. I crafted my two keys and used the first one. I got malph champ. I opened the second one but Nothing happened. It just vanished. I went into the lobby and came back to see if Something went wrong but it was the same old screen without new skin/champ/whatever and both chest and key expired. I restarted the client and got Nothing back. It's not a big deal because it wasn't bought-content (free chest and free key) but still a bit annoying :D
