Zac health bar bug

Unfortunately I do not have a screen shot, if it happens again I'll report again with an attached file. There have been two games so far I have been playing the champion Zac in the jungle and my health bar has been black. The health bar will not be green like it is usually, instead the bar will be completely black like I died. The health bar fraction (Current Health / Max Health) in white letters is always there. Also upon me taking damage from any entity, my entire health bar will blink red. This is a little annoying on my first clear where I'm constantly monitoring my health, however it doesn't effect game play at all. I would also like to mention that the health bar discoloration stays this way through the entire game, dying or reconnecting does not fix the coloring of my health bar. Any help would be appreciated, thanks.
