Ever since the last patch, I've had a problem with the health bars. I had PerbUI mod since like last year, and when the new UI was put in everything but the health bars were changed for me. I eventually forgot I even had the mod. Now in the game the UI looks like it does in these pictures. I have to turn colorblind mode on to make it look somewhat normal. I already tried to repair the install for LoL from the launcher and it didn't do anything as far as I can see. I would be fine playing with colorblind mode on, but I can't see how much health someone has without clicking on them.
