So I have the following map:
I've found the deed using Archaeology, in the desert south of fog lake.
As you can see there is a guard tower just east as well. There's no question this is the correct area, but I did a little more scouting to see if I could find something to match up to the crossed swords on the treasure map. Looking north from a high point south of the area. I did find a spawn at about the correct location. Sorry the panorama is so bad, I couldn't get the perspective quite right:
At this point I've dug for treasure every third tile moving out from the tower for 50 tiles. There are less than 100 tiles between the deed location and the tower itself. I then dug out to either side of the intial line by 3 and then 6 tiles to both the north and south. I can't see how I've not found anything based on this location and map.
campfires are the initial line of searching.
I don't know what else to try at this point aside from digging on every single tile in the area, and I'd rather just go play something else. Is this just another pointlessly opaque and tedious system in wurm or am I doing something wrong? Probably both..
