I believe all class quest for crafters are a lil out of whack right now, with some being less manageable than others and all requiring you to do dated synths to complete or buy the dated cloth/leather/insert w/e here off the wards. Leatherworkers must be a little more effed, I think the quests are bonked for now, and while thats not right by 1.20 they should have the quests converted over I believe since all dated synths and items will be taken out of the game.
