The gnomergan questline added in SOD gives a teleport from booty bay Scooty to feralas. However, during the quest steps, if you loot Corroded G-7 C.O.R.E. Processor and don’t talk to Ziri inside gnomergan, but turn it in to the gnome in feralas directly, you can no longer obtain the Quadrangulation quest. This also means your character will never have the booty bay to feralas teleport. Missing a great inconvenience feature due to a quest bug should not exist, please fix this issue.
