basically the latest curseforge api update means that your mod has to have this checked otherwise only manual downloads/curseforge launcher are capable of downloading it

I use this mod in my Vanilla+ modpack and would love for it to be able to be used again

Because Curseforges api turned out to be such a mess, I'll upload EntityCulling later to Modrinth later today (#30) anyway. CurseForge modpacks = CurseLauncher, any other modpacks = other launchers = modrinth.

https://modrinth.com/mod/entityculling is the url as soon as it's approved/processed.
