Go figure, new mechanic, new bug.

So, got one of the new influenced maps with the affix that rare enemies have the fireball that chases you when they die...I always forget the name of it...Volatile Cores I think?

Well, half of them are invisible. Never visually show up. Died 4 times checking it. Kill a rare, run 2 screens away, nothing on screen, explode and die. Kill a few rares, see a couple balls, dodge them, get off screen, die with zero things on screen. No debuffs, no DoTs, no multiple hits, just 100 to 0 in an instant.

So...don't run that affix if you like your exp.
