The HUD disappeared

So. I log in to play a game, a ranked game, and the HUD is all weird. I can't click on abilities to level them up, and the character symbol is all grey at first. Then, when I level up q using ctrl+q, the HUD disappears altogether. No abilities, no minimap, no topright corner (kda, cs, game time, ping, and fps). Nothing. It looks like COD on hardcore mode. I had to quit the game and relog to play again, and at that point, the game was pretty much over. Can you please, please fix this game. It's so obnoxious to lose a game or have wrong runes just because the client bugs out. It happened when you created the new league client, and now that Runes Reforged is out, it's happening again. Please fix all the bugs so I can get back to business as usual. [zombie-nunu-bummed]
