Im hoping this isnt a corrupt map? (It has been converted and this is a copy of our live server)

If you use both with default = TC not working for you.
Duno why you use this ..
Anyway will be fixed in next build.

What terrain\biome mode you use ?

They are both set to default

Edit: Interesting, I set them both to normal and it loaded without any errors.

We had the world already generated using previous settings but we use a border region for resource renewal, the newly regenerated border terrain was kept as default (for resource reasons mainly)

But thanks for the help, me and my players are very happy we can update now, and even happier we wont lose the map. :)

Try use latest dev version :)
