Good news and bad news! Found the problem... not sure of the proper solution. The problem is the size of your ecosystem objects in comparison to the resolution of your terrain. My guess is that there's some magical ratio we should follow for this kind of stuff, but don't know what that ratio should be. Basically, if we want to use maps for distribution, we need to give Vue more resolution to work with. I usually start out with 1024, which is why I didn't have the problem. Anyways, now you know where the problem is, so you can focus your attention on that. Have fun, Stewart!
