I'm playing a modpack called "Stacia expert 2", I'm looking for iesnium ore, I use my divination rod but it's not showing me the direction or where the iesnium might be.

Ps: I've tried changing the divination settings in the game files and I'm using it as a "bow", that is, holding it until the end.

I've used the mod before and I know how it works, but it's just not working.
