So i tried to make a vampire npc, all well and good i thought, Npcs i added to spawn in biomes spawn at day are fine, But they will never spawn at night i wait and wait and nothing happens, I try to force them to spawn at night but even the monster spawner will not function at night only at day, this is a very annoying bug that i hope will be fixed some day. with another suggestion could i use another mod like incontrol to force the entities i made in custom npcs to spawn at night? I am really bummed out about the whole thing ?
