Treasure maps are all in the same map grid - singleplayer

[CpbujagoTokuja 0]

So I started a single player game on PC on the Ocean map about a week ago. For the past two or three days every map found is for grid H6 and only H6. I haven't yet ventured that far from B8, C8 and a little into D8. The maps still vary just as randomly in quality though. 

Anyone experienced this or have any tips to fix this? Any mod suggestions that change up treasure maps to sort this out are most welcome too.

Anyone who finds a way to fix this for me gets a drink, I promise.
