This is what happens when you change jungle !

gg, buff smite, it's doing nothing

I've seen it happen even prior to this patch, some graphics replaced with Flash icon. I have heard that it can happen if you alt+tab out during the loading screen. It has never happened to me after I stopped alt+tabbing, but who knows if that's the real cause or not.

I have seen that glitch for quite the long while now, but it's generally with flash and heal icons as particles.
