Bug: I loaded an autosave from an early turn, the one after Edmund returns from breaking Impish Jaw. There was a council vote on healthcare. Trinculo’s response before the vote was “Thanks commander, 100 Imps lost bits working on your jetpack, so this is the least you could do” – before I had voted. I'm pretty sure he's supposed to say something different before you vote. Going for the Undead arc this time, I turned down the healthcare request. The Imp’s dialogue didn’t change.
Isn't it brought up by the elf because a dwarf lost a leg working in the mines and now is in need of help to get a prosthesis? The imp says that imps regularly suffer such injuries, so he's in favour of the proposal. Makes sense, I think.
Or do you mean that the response of the imp doesn't change after you turned it down?
