There seesm to be a bug when travelling outside Isendel and coming back in.
When leaving the island it says, "You can leave the island using a one-way portal, but if you go to other places or fight their invasion, you will need to travel back to the island via ferry or ship. Continue?"
Without going anywhere else just leaving the island and coming right back it is asking me to pay the ferry and 10 energy or 5 energy with ring. I thought one only needs to pay if they go to other places.
