The Dink Network

Oh man, I was sailing happily along, almost to the One Tree Isle (I think) and on the locked screen where there are three Octopi after me, I somehow got outside the hardness area and for the life of me cannot get back. Guess I'll go back to another saved game, but has anyone else found this?

also--Should I be able to edit the hardness on this tile? I went in to edit it and I was able to add hardness, but not soften it. (question from non-programmer but one-time author hopeful)
