Quick bug report. There is a softlock present when you let Penelope take full control in the ghost ship bit. Its entirely possible to spirt away back to town using the anchor to body skill, and since Celica's ghost or the people she possesses cannot go to the treasure cave, or use the mirror to go to the ship, and confronting penelope on the ship is the only way to get your body back, it resulted in a full lockout that i had to reload
