Villagers don't attack creepers (I guess to avoid them blowing up villages?) And skeletons are also considered passive. But they attack me when I rely on the village guards to protect it.

So, Where is the Config file? Is there a video of how to modify it, what application is required to open it
?

Okay, I did some looking into it, every time I changed the file, it made a BAK file, And the BAK file did not change, so I had to edit the BAK file, and delete the other BAK files, I have it all working now.

Works as intended.

You can enable guards attacking all hostile mobs in the config.
