Running on Java 17.0.8 (Debian 12)
Magma version: 1.19.3-6e6ce905
Bukkit version: v1_19_R2
Forge version: 44.1.23

I'm having the same issue as #84 but in Magma 1.19.2.
Whenever I get close enough to a village these warnings pop up on the console:

Please let me know if this is a magma issue so that I can report it to them instead

Honestly I'm beginning to believe this is a magma issue since "target reason" doesn't exist in base game forge minecraft. Test it on a non-magma environment and see if the same error appears. If it doesn't then it's a magma issue.
