Large World Issue

I have considered this and I wish I could talk directly to the guys that make kenshi cause they dealt with this exact issue and they did it before world comp existed. But my world is designed as a proper geographic land mass oceans, rivers, valleys and islands so artifically placing impassable terrain like mountains would destroy it. So I was thinking what if I loaded the heightmaps in in squares. An example of this is a large island one of the largest in my map I rectangled it so it was surrounded by a sliverish of ocean and was only like 12 tiles out of the 2096 and read out as being 60km2 so basicly 10x6km and the world bounds still cut it off. The theory i had was line em up but use minizoning kin to asheron’s call and dark age of camelot to load into a new world bound or even overlap the world bounds so that a player near an edge would be inside two world bounds but streaming only the nearest tiles to thier machine to keep load low. Problem is even my island cuts out and i can’t edit the whole island cause even in editor i end up with portions of the island missing from view.
