The fletching tutor, Alison Elmshaper, is supposedly in Taverly, but she seems to have disappeared. Online sites says where she used to be, but she's not there now. I've also searched the world map in-game and not found her that way either.
There is some kind of dungeon near where her shop used to be. Did they accidentally overwrite her with the new content?
I found this in the September News (https://secure.runescape.com/m=news/c=HyegAYiBTEU/september-mobile-update)
Skill Tutors The number of skill tutors in both towns has been reduced, and those that have been removed have been placed in more appropriate areas. For example, the construction tutor will now hang out at the Rimmington house portal. In other cases, tutors have been combined to provide instruction for multiple skills.
Tutor shops have been cleaned up, so they will no longer attempt to sell tools that are provided to players in their default toolbelt, for example.
Fnally, skill tutors will no longer provide their own challenges, which gave no rewards and, because of their overhead icons, were frequently mistaken for typical MMO quests by new players. ----
Not very helpful regarding details about which were kept/deleted and which were moved/combined.
