version 1.8.26

Playing modded survival, following CaptainSparklez new youtube series, so running a number of other mods, but Lord Vatticus and the other named traders from this wiki page, https://divine-rpg.fandom.com/wiki/Lord_Vatticus, are not spawning. Travelled thousands of blocks looking in every room, stayed in open areas killing mobs, checked the roof, and they will not spawn. The only traders that I have gotten to spawn are the war general (In same style room both times) and Leorna (in the room with farming on the left and right), who do not sell the items needed to spawn the bosses.
