After 1.18, the caves and cliffs update, all hostile mobs spawn at light level 0.

Wandering warriors and hans the mighty however, spawn at light level 7. This leads to immersive weapons mobs being the only ones spawning, in well-lit areas at night.

Release Date: 6/13/2022
File Name: ImmersiveWeapons-1.18.2-1.17.0.jar
File Type: Release
Game Version: 1.18.2

I'll take a look at it within the next few days. I definitely didn't modify the light conditions to match the new vanilla spawns. It should be an easy fix.

Thanks for the report!

This is now fixed in the latest commit on master, for 1.19. The release should be available shortly in the repository and on CurseForge.

I'll get to 1.18.2 soon.

Thank you! :D

There is now a release for 1.18.2 that has the bugfix included. Sorry it took so long!
