I can't talk to Vanille. It says "meet up with Vestia at the Blue seal", but when i try to talk to Vestia, it says "I should check on Vannile! Lets take a look west of here". Vanille is the storage right? i can't really take to her.
You're meant to help her by adding a seashell into the pillar in the room she's in! You should have one in storage (but you can find more in the ocean by clicking the pink shells), you'll need to take it out of storage, open your inventory, drop it, close the inventory, then grab it with right click and insert it into the pillar slots. You'll be able to progress once all 3 slots have a seashell ^^
