I’ve produced this bug twice now. If you go after Aurion on Wildwater Island you are flagged normally for the day under Field Boss, however with Aurion you are also flagged for Ghost Ship for the day.
First time I was like “strange, I don’t remember doing any 1370 ships today”, so this week I tried Aurion again. As soon as you are finished with the island battle, ghost ship get flags as well.
This is happening on NA West Coast
I’m not seeing anybody else report this but it has to be a bug because Aurion isn’t on a Ghost Ship.
