Blight monsters Bears ignore CC / towers / player aggro and rush pump

Once they spawn they will rush at your pumping machine

They ignore everything: player, player minions, tower minions, all forms of crowd control (slow, freeze, tower-minion-made stun, phys-made stun)

I have checked. There are no map mods that could let them do this. No altar mods. Monsters came from phys-resistant portal, but going through a multiple fields of freezing towers didnt impede them at all. Also mobs ignored me and minions wholly.

This Only happens with Bears and Bats (altho less often).

This is my 4th failed blight event today. All because i dont have big-D DPS build and need to rely on towers.
