So after some testing using the https://whitelist.gorymoon.se link to generate mobs I found that they would only generate if there was a name in the "Mob Names" = [""] section of the config as well. If I leave it blank like this and have my csv list from the site connected to the config no playermobs spawn from that list. if I put a player in the "Mob Names" = [""] part then it will alternate between spawning that player and the players from the csv list. Im guessing this second outcome is expected but was hoping that we could spawn players using only the CSV list and leave "Mob Names" = [""] this part empty

Can't replicate this, mobs spawn with names from the "Name Links" links with names in the "Mob Names" and with it empty.

CSV files/links aren't supported, only newline separated files are supported.
