Lost World - Please Help

[slopsbucket]

Aaaarrgh!

Another power cut while I was playing, and this time replacing env_meta.txt didn't help much.

My world opens but my castle isn't there any more. The sqlite database appears to be about the correct size but the world is empty. I had 2 more levels added to the main keep, a proper gatehouse and everything.

Please help, any suggestions on how to retrieve it would be appreciated.

Out of desperation I figured that as long as the database itself isn't corrupted all the rest is mostly irrelevant fluff, so I tried putting the 2 sqlite files into a different world's folder and it worked.

One of you smarter people would probably be able to tell me which file is corrupted but I don't care, I haven't lost many days of "work". I'm so happy.
