I've searched all the DS forums here, on Steam, and other DS sites. There are a few mentions of blue-highlighted items not opening but I haven't seen any reply on how to fix or get around this. Without the Elddim townstone, you cannot get the prophet ring and therefore cannot get the other townstones. You can have fun playing the UP map but you lost much of the playability. Does anyone have a solution, suggestion, or link that might assist?
