The NPCs on the Captain's Station (you know, the supposedly prestigious club for paying life-time / long-time subscribers) have been eating up my regenerators/components for the longest time, and I finally found the reason: I believe it is because the interact button on them wrongly triggers the regenerator/component interface, instead of the interface used by the injury removing NPCs on other social hubs.
For example, when you go to Chief Medical Officer on ESD, they greet you with a "Treat Officers" prompt, and when you follow through, they immediately go to interface for treating your injuries, regardless of your target. Not so the NPCs on Captain's table. When you hit their "Treat Injuries" prompt, it will open an interface to treat the wounds of whatever you are currently targeting, exactly the same way as Regenerators/Components used from your inventory do.
You can also see the difference on the screenshots below: One interface clearly uses EC as the resource, with price of service being 0ec, while the other interface uses regenerators instead:
So, now that we have a shiny new entrance to the Aenigma Nebula, could we maybe also have all the amenities on board the station working properly as well, pretty please? :-)
