Anyone knows which version of Diagonal jagged edges is for the Sudden Valley Terrain?
A DJEM modifies properties included inside Terrain Exemplars, meaning if you use both mods, the DJEM will need to load after your Terrain mod to work, but that might have unintended effects that mess with your Terrain mod. The better solution here is to edit the settings for the DJEM within your current Terrain files, instructions for that are here (http://community.simtropolis.com/omnibus/simcity-4/tutorials/know-your-terrain-a-simple-guide-to-making-the-most-of-your-terrain-mod-r250/).
