I didn't found a smart solution but the reason of your problem:
the textures will be reduced, to the ones you used, BUT the already textured landscape is assigned to the order before you've changed it.
E.g, a texture which had the ID 23 may now have the ID 2 -> if you have now a texture with the ID 23 it will be assigned, if not there will be shown 'Texture ERROR'
possible solutions:
-> retexture everything
-> edit the cfg: replace every texture you do not need with another texture you need (to keep the order)
-> choose next time at the beginning the textures you want to use and delete the other textures in the cfg
