I see that as well with the debuff Icons. Whenever I get a temporary debuff from a Massacre Bonus, killstreak or a shrine, some of my other debuffs change to the same debuff-icon. This makes it hard to see which debuffs are active at the Moment.

Additionally, the perk "Attack Anchor" seems to have worked only once(!) for me, and never again...

And if you don´t mind me tuning in as well. When mobs throw grenades, it sometimes get stuck and explodes high in the air.

I know, not much. I know. But it´s a bug, so I just felt like mentioning it.
