Mob Agressive AI in the new version

Choosing to base your mob AI on "None" and adding the Act agressive against AI won't work, it just wont, the mob wont attack you no matter what 

I usually fix this with just basing the mob AI of Zombie or Wolf, but doing so messes up the drops 

If I base it on wolf it won't drop anything, but will attack, and if I base it on None it won't attack but drop the right item 

Any tips??
