Is this intentional? if it is can it be turned off in some way?

It's kind of annoying to just be walking through a cave and be jumpscared by an aggressive cave dweller because you looked the wrong way and angered a cave dweller in an entirely seperate cave system,

and it also messes with the flee behavior sometimes, because the cave dweller thinks you can see it when you can't

If you're on 1.19.2 you can test this version if you want
https://github.com/SiverDX/cave_dweller/releases/tag/test_build-1.19.2-1.6.2_v2

It was intentional to turn it off since line of sight check Mojang has can have issues with certain entity sizes / 1-block-wide holes
I added it back now for a certain check

Might tweak some other parts in regards to the flee behaviour

perfect, thanks, unfortunate i play on 1.20, my fault though

Should be fixed in the latest release on CurseForge
