[CLIENT] Hextech Crafting "crashes" client?

This has happened to me twice now and only recently, so I think it must have been spaghetti'd into the last patch or hotfix, but basically clicking the Hextech Crafting and Loot button shortly after exiting post game lobby causes the client to crash and I have to restart it and log in again. There isn't really much else to it, but it never happened before the past few weeks.
