Rengar bugged in Nexus Blitz

​In Nexus Blitz after the URF event Rengar is permanently missing 200-500 hp for the rest of the entire game. It looks like you can heal the missing HP with W but you cant, and even if you die you are missing that hp. Its not just a visual bug, you actually are missing that HP. It also makes using your W deceptive since you visually cant tell how much you are actually going to heal (it shows actual heal amount plus the 200-500 missing HP that you cant heal). I reported this bug several times on the PBE forums before Nexus Blitz went live, but is still there on live servers. This bug NEEDS to be fixed, missing200-500 hp as an assassin really sucks. When you are playing an assassin you only have around 1800 hp, and missing 500 hp is a pretty large percentage.
