I'll have to redo it. Simply increasing the size will introduce too many problems and I'll end up having to go back and tweak everything anyways. If I'm going to have to tweak every step then I'll just redo it at 8,000 and then you can shrink it if you want. I won't be able to post it here on the guild, though, so send me a PM with your e-mail and I'll e-mail it to you in a few days (with rivers and deserts).
