All in the title; basically I've created landbridges for my mod, and made a few geographical tweaks to the game - in order to do that I had to add new terrain in descr_heights. Unfortunately I now have issues with jagged edges in the parts of the map I've modded, and am at a loss as to how I could fix the issue.

Anybody got any ideas? Any suggestions or help would be greatly appreciated.

I've attached a collection of images of the map that highlight the problem.

Thanks for your time!
