I've been thinking and since the previous build had no sort of room claiming element to it, the portion of my post about the hills in the dungeon MIGHT be better off as a design discussion. I had originally assumed the holes in my dungeon were the result of a bug since they hadn't happened at all in the previous build. With where the hills are appearing, they are messing up any sort of dungeon layout that looks nice and causing me difficulty in making an efficient and secure dungeon. I'll post this in the appropriate thread as well but since this is here. I have 2 solutions in mind that wouldn't change much and would solve this issue. 1) The ability to smooth out hills so they can become the cobblestone floor that is claimable, 2) Allowing a hill to be claimable IF it is adjacent to a claimed tile already.
But lets not let this overshadow the thing IM sure is a BUG and that is if you use the claim tile tool on any unexplored area of the map it will reveal that area to you forever, removing both the black and the fog of war permanently. If I'm not making sense I could whip up a short video clip and show it.
