I had this experience too recently when i went there lol. I guess it's one of the reasons it didn't get much love on gms either. Those drake maps that came in the dungeon revamp are pretty meh too =(.
Just wanted to add that I tried to fix the Owl of Minerva back then. I was able to determine which item was been searched for, but wasn't able to pop up the screen with all the stores listed, prices etc ( this one). Simply because there's no way to tell what data to send to the client. Probably if I fixed using custom scripts on NPCs earlier, I would've decided to show the results in an NPC chat, but at the time the only option there was, was dropping all the information in the chatbox. Something which is functional but isn't appealing.
