Hextech crafting/play again

Hey all!

Dont know if this has been reported or not, but I didn't see this in the board.

Every time I finish a game and try to go into hextech crafting, I have an issue with the client disappearing. It mainly seems to happen after I've selected play again, and it often interferes with the queue. For example, about 5 minutes ago I had the issue, but immediately before it disappeared the lobby accept popped up and I hit yes. I have no idea if I dodged or not. The issue is not that the game crashes, but rather that it stays active but the window disappears. No sounds, no visuals, no popups, no anything. It's like the game has closed, but when I go into the task manager it's still showing the client running. If I wait long enough it sometimes reappears (I'm talking 10, 15 minutes). If I try to reboot the client, it tells me that another instance is already running. It's vastly annoying.

>>TL;DR >>Finish game >>Hit play again >>At any point before or after entering queue hit hextech crafting button >>Client window disappears >>Still running in task manager >>Wait long enough and it might come back >>Queue dodges abound >>Mad

What other data do you need to diagnose this problem? More detailed steps to recreate? Frequency of occurrence?
