[EDIT] Fixed my own problem. I had made three terrain textures and two of them were not showing shadows over their surface and seemed to be drawn "above" the rest of the terrain.
Turns out I left out half the normal map on those two. I cut the red channel from standard normal maps but forgot to paste it into the alpha channel leaving the alpha totally white. Made the normal look kinda flat and seems to have affected how the shadows got drawn too.
I used the normal from the terrain that worked to find this out, then opened up the two broken normals to see what I had done. After adding in the other channel in those two normal maps, they work fine. I've attached the updated version of the map in case you want to see.
