I can see the snowmen before the event but as soon as the event begins the static snowmen disappear. As the event plays out i take damage from the invisible snowmen, also if I target a player targeting a snowman or happen to target a hidden snowman my game crashes.
I haven't seen the regular snowmen disappear during the attack but on occasion I have seen the Snowman Overlord go completely invisible but I am still able to target it and attack it. Very strange indeed.
I use to be with it. But I don't remember what "it" was. Now what I'm with isn't it, and what's it seems weird and scary to me.
