Are those available for games that are underway, or do we have to start a new game to see them?

It's working on my end. Do note that the followers have the tag 'can only exist once'. If they have been spawned in at all, even through console and deleted through console, that character wont appear in the loot pool for the rest of that ascension. Make sure the mod is enabled. I did make an error in my description, after just checking. If you updated mid-playthrough, they wont appear until you start a new ascension. I didn't actually change the uniqueness group ID so they cant spawn until the uq id is reset, which will be on a next ascension. I'll change the mod description to note that.

So the followers just aren't appearing ingame and after opening the console I think it might have something to do with the long string of "NONEXISTENT_ID" error messages

no idea how to fix that though

this isn't working for me, anyone have any idea why?

Looks so cool, Thank you for sharing!

Great art. Thank you. < 3

Cheers! Thanks for the mod!
