Steps:
1. Attempt to sell Qutrub Bandages to either of these Guild Salesroom NPCs
2. A price is listed next to the item (37 G), but the item name is grayed out when attempting to actually sell it, suggesting a full guild inventory
3. But neither NPC has any Qutrub Bandages for sale, suggesting an empty guild inventory.
4. No messages are displayed in the log to explain the guild's failure to purchase Qutrub Bandages
5. I've tried over the course of two earth days to ensure inventory numbers are up-to-date, to no avail.
6. Other items (e.g. Imp Wings, Chimera Blood) work as normal

It can't be sold to NPCs, due to being listed under beast-made.

It's a guild salesroom. Guild salesrooms only buy the specific items they list. Qutrub Bandages are listed, complete with an offered price (which I noted).

Go talk to them yourself if you don't believe me.

At any rate, it's behaving as if I have the bandages listed in my bazaar, but I don't.
