Homunculus vs. custom monsters

[Nachi]

Yo!
Have not found any topic about it with the search function, so i'm opening one.

I tried to get my Lif to attack the custom monsters on poring island. By default, she ignores them completely. Even when i order her to attack, she often ignores them, as long as there are other monsters within reach.
So i got the monster id using @mi and entered it in the ai panel, setting it to "attack". (Yes, i saved and relogged/restarted, before anyone asks this. xD)
Yet, i'm still getting the same behaviour on my lif.

The only monster it actually detects and attacks without me having to point to it and right-click like crazy, is the pouring, probably because it's aggressive.

So, is there a way to configure my homun to attack those custom monsters?
