Fix the client please.
It's fine that I don't load into the game sometimes when my loading screen hits 100%. What isn't fine is that I don't get any error message or any sort of indication that something is wrong until I try to tab out. It also doesn't help that when I do try to tab out, nothing happens. The only way to close the loading screen is to sign out and resign into my computer.
And what definitely Isn't fine is that I lose LP for it. This has happened on 3 different computers on different occasions for the past year or so, and it's ridiculous
