Problem with render height

[octaves 4]

OK, so when I FINALLY finished rendering my map this morning, I was not so pleased to see that the heights were completely messed up.

Heres a picture:

That low lying area is supposed to be water!  And the lands all pixelated too!!!

This is flamesrock's Columbia River Delta Extended Edition that I edited.  All I did was basically cut out the actual delta and left where Astoria would be in real life.  (You can see where the piers would be)

So Im wondering, what happened?  On Landscape Designer, it said that would be water and the land showed up pretty smooth..

Please help, dudes!  Thanks

You may already know, some of Flamesrock's maps need elevation dat files. But, what may have happened, is that the entire map did not render. Mallowthecloud, sometimes suggests loading the cities and saving to see if they did render.

Yeah I checked some of them (This is a huge map) but Im wondering if the erosion mod I just downloaded has anything to do with it...I guess I should TRY to re-render without the mod...Oh god, see you in another 7 hours

If it is that big of a map, you may not make it. But good luck.
