Ahoy! I've a few thoughts about doing maintenance to that quest. Listen.
1. While in Hamamitsu Skyway, Ratbeard's line, "You should get that thing back to the Tea-keeper before he gets a mind to double-cross us!", should be changed from a dialogue box to a dialogue pop-up.
2. While talking to Sosei Wearu, the camera should focus on him while he says his line, "Oh my! Is that a fine Statue of Imperial Jade in your satchel, or have you come to request a noodle-house permit? Both? How fortuitous!".
Those are the only thoughts about doing maintenance to that quest. Hope that gets done soon. Thanks!
