I thought maybe they would auto unlock with the dragon sigils, but no luck there either.

Yes, research notes are a currency.

I noticed this myself, but I moved all the items it tried to salvage into my invisible bags for safety. Did eventually try to salvage them, but turns out that you indeed can't do it. The items include Mortar Seed Turret, Ogre Pet Whistle, Tuning Icicles, and Fire Elemental Powder. Edit: Also Lumps of Crystallized Nougat, Flasks of Pumpkin Oil, and Sharpening Skulls.

The issue with Treasure Hunter is a different one. When magic find was removed from gear, many drops that had magic find was changed or replaced. Possibly as a side-effect of this, now bosses that drop trinkets part of Treasure Hunter often drop bugged versions of those trinkets that are fine level 80 trinkets with a single Condition damage stat and an amber pebble upgrade on it, instead the level 80 exotic trinket. So players will often get something like this:https://wiki.guildwars2.com/wiki/Sam_(fine) Instead the appropriate version:https://wiki.guildwars2.com/wiki/Sam Getting the bugged fine feels worse than not getting anything at all, since there's no way to 'upgrade' the fine version to exotic, and the fine version doesn't even have proper level 80 stats, so it can't even be used to equip it Those bugged versions should just be removed.. I have looted both the exotic and fine versions. It's not broken at all, just rare.
