Thanks for the attempt Hoplosternum. My map isn't that great, so I'll accept this as a training effort (I learned a few more things about how not to make random wrapping maps!) and use one of the maps you suggest. (I'll also send a message to llamabeast so he knows there's some kind of problem, but that need not delay this game.)
Anyway I like the looks of Alexander. Here's the link to that one:

Sorry for the confusion people!
Also, does anybody know what the logic is for whether you can edit a post? I seem to be able to edit some posts and not others, and I don't understand why. But in the meantime:
HEY EVERYBODY PLEASE IGNORE THE MAP I UPLOADED AND USE ALEXANDER INSTEAD: http://dom3maps.wikidot.com/system:alexander
