This is a mod to fix a couple of issues with Deirdre at the Slog. She’s supposed to be a trader, but you get a blank trading window when you talk to her. Also she’s not marked protected, so unlike the other Slog residents, she can die during a settlement attack.
This mod sets her as protected and fixes her ability to sell stuff.
Thanks also go to Mogomra - while trying to work out why stuff wasn’t working, I stumbled on their PC mod to fix Deirdre, which clued me in as to where I was going wrong. This mod admittedly duplicates what Moromra’s mod does, but it’s all my own work and importantly (to me!) works on PS4.
As far as load order goes, the only one I currently use that it conflicted with is “Scrap that Settlement” - this mod should be above that one in the load order.
