Damn!

Well that's weird because the map converter seemed to work for me. I have converted quite a few maps with it and all worked OK. Could you tell me 2 things:
1) Does the map editor give any error messages?
2) What is the size of the files produced by the converter?

I will have another look at it today. I really ought to test these things properly before releasing them

Bridges are models AFAIK, but I haven't done anything with water yet, so I can't be 100% certain.

Thanks for the feedback!
