Last game I experienced opac minions.

This made laning a little frustrating because I was literally looking right through them. So it was hard to gauge which minion had what life. On top of that, and I don't know if this created or added to the bug, I was facing Yorick. And his gravestones, which are already of lighter color, were also opac; making them near impossible to see. I'm really hoping this is just a 1 time fluke but on the off chance I am reporting this.
