I am having a strange visual glitch when Hesperus is installed. my server has a mod called Advanced Holograms, it's only server side but for some reason i'm seeing what looks like leads coming from the hologram to different entities. I have pictures and can link you to my modpack for further testing if you like: my modpack: https://www.curseforge.com/minecraft/modpacks/the-valley-1-12-2 Advanced Holograms: https://www.curseforge.com/minecraft/mc-mods/advanced-holograms

I have completely removed Hesperus from both server and client and this issue is still present so it is not your mod causing this, it's strictly Advanced Holograms.
