Minions dying all of a sudden.

Not sure what changed. I recently made the jump to cluster jewels (im level 91,) but this started after that. I've ran plenty of maps since that change. Now my spectres, zombies, and skellies are all dying in normal packs. I have not had any issues at all like this since I started this build.

Edit: Guess this was two of my very first maps with physical reflect... crazy that I haven't "inadvertently" ran one of those prior to level 91!
