Visual Glitch: Multiple Devourer Wolves (Shaco specifically - Picture included)

In the picture above, you can see a picture of a dead Shaco, surrounded by wolves. Specifically, 3 of the bright wolves that follow you around, on top of a bunch of brown ones. This is the second time I've seen this. The first time it was in a normal, and the brown ones werent there, but it seemed like every time the shaco ulted, he'd get another wolf. This time, I was spectating, and for some reason see a bunch of brown one's as well.
