I believe the tutorial popup window on torches shows up in the Ancient Ruins (or whatever those ruins are called that Shadowheart is trying to get into). However, it might only pop up if you go in the expected entrance, through the locked door past the bandits/explorers who call dibs on the Nautiloid crash site.
The torch tutorial should be on the actual tutorial on the ship, given that not everyone investigates those ruins. And/or it should simply be "use"
