Yep, We've all experienced that. Just run bruh. Run as fast as you can until they can't see you anymore. Hide under a rock if you can. That'll save you. XD

Haha!

Just in case this helps anyone until it gets fixed:
AoE (Area of effect) skills seem to kill them for now. At least it worked for me. Otherwise, yes the running sounds lie a plan...they're not too fast.

Bats in all area are 90% bugged

The problem is not the bat themselves, it is a hitbox problem with little size mobs, il is very difficult to aim some of them while their hit boxes are located far under the mobs themselves

if you put your cursor on this type of mobs sometimes it won t target them, you have to put your cursor more than a little bit under the mobs ...

same problems with somes mobs from act 2 , some kind of worms with open mouth that cannot move, when you cast a projectiles on them the projectile will head for the head, but their hit boxes seems to be located on the ground where they were pulled from

Same problem can target them (red line around them) but not hit them. Melee aoe does the trick but im runnig ranger now so no luck. Got surrounded by 3 bats cant get out cant hit them just sitting here waiting to die. Bloody annoying
