Maps for all Buried Treasure in the Game
 

Anyone have any of these?

I've searched around the forum (a little) and Googled stuff, but I haven't been able to find a map or even a list of buried treasure per area.

There is no such thing, as it is randomly generated where buried treasure appears upon creation of a new game. Same is true for available troops, items and map goodies (ldr flags, runes etc).

There might be hope since mods can scan every savegame for its properties. Maybe there is a mod that can display some sort of coordinates for the treasure hidden. That is just a suspicion tho. The savegame scanner can at least tell you in which land the treasure is that it has found during the scan. Not sure if it displays coordinates or hints. Search the forum for the term savegame scanner and you'll know more.
