(gameplay) Hud numbers disappearing.

I was playing a ranked game, and in a minute, most of the numbers were gone. The CS counter, KDA's, the timer, the cooldown timers, the passive numbers, mana costs, mana, HP, names, etc. They all disappear, and for a minute everything (hud) but the minimap were invisible. Bugs like these in ranked games make the game a WHOLE lot harder. Though I could see how much gold I had while looking at the shop. Of course I lost the game. It just sucks how I get disadvantage in a ranked game because of a bug. This isn't the first time my hud messed up.
