I have been putting lots of effort into burying treasure, but with the NPC generated treasure maps, its easy for a good map to be lost. I would suggest that any map placed by a player should be bordered in gold when looked at on the board at the docks. A good few players, especially newer or poorly informed crews, will likely assume that all maps give two small items, like the automatically generated ones do and they will just start to ignore the board and anything placed on there, especially if someone has a name, (like mine), which fits with the npc naming style.
At the very least, if someone places a "hoard", then that should be highlighted. That way someone can immediately see that a high value map with many items has been placed.
