I've created a follower for a new mod and I want that follower to also be a merchant. Everything works great until the follower goes outside their original cell with you. When you leave, they will only sell their inventory items, but nothing from their merchant chest. It gets stranger. There are a few follower-merchant mods on the nexus. I downloaded and tried them all, and this bug persists with all but one of them (Ren Wolf). But in all cases, if I ask BOTH my follower and the downloaded follower to follow me, they somehow correct each other and I can then buy stuff from them outside their original cell. Then I can dismiss one and the other will continue to work as intended (I've played for about an hour and did quests, etc, they restocked after 48 hours with new leveled items when I hit the required level). Things I've tried: removing AFT; copying Ren Wolf's factions and merchant chest location; adding factions that correspond to the merchant chest location; console command remove and re-add factions; change relationship to player; and some other things I'm probably forgetting. My working theory is that the second follower somehow forces a cell reset when you ask to see their items that affects the other's chest. So when you talk with the first follower afterward, they again stock their regular items. I could be completely wrong. I could really use some help, I've been working on this problem for a few days and haven't made any progress. What could be causing this and what could I do to avoid it?
