As far as the npc detection, there should be a button on the GUI that lets you add an NPC’s face colour to the list if Duelit is ignoring him. Should also work for any loot colours it misses.
Thanks for the reply!
I’ve tried the “add NPC” button to add the NPCs and loot it’s missing, this didn’t work. I don’t think it is the pvp settings either since it is not even completing all the duel world duels, therefore not coming around to trigger the pvp battles.
