Thank you Greebo, and that little jog in the NE waterway was an accident that I decided to run with because of looks. I'm looking at other ways to balance it back out, but I don't think it will affect it all that much since I'm trying to keep the bases around those waterways relatively similar distances from the waterways. Another option is to reduce that side's width and make that jetty an island, thus placing the main waterway back where it should go.
Right now, I'm practicing height mapping. Does anyone have some rules of thumb for height mapping? (max height, things to watch for, etc) Also, is there an easy way to place grass tiles on any square that is over 0 ft? It would make it much easier to back through and have a starting place.
