I've had my LotGD running for about a week now, and I wanted to activate the "Multiple Cities" module.  I went into the SuperUser Grotto and activated it.  No problem.
I go "Back to the Mundane" and, hey, there's no forest anymore.  I deactivate the "Multiple Cities" module, and the Forest comes back.  

I'm using v 1.0.3
The game is at http://www.caernest.com/logd

Anything else I can tell people that will help?  I've looked for similar problems going thread to thread and didn't find anything.  I've also used the search button...  
I hope I'm not bringing up something that's been brought up before.

Just for the record:

You could have read the FAQs on your server...  *lol*

There it says: "Frequently Asked Questions on Multiple Villages". Following that link leads you to:

4. Where's (the Inn, the forest, my training master, etc.)?
Look around. Do you see it? No? Then it's not here.
The problem's usually:
a) It's actually there, you just missed it the first time around.
b) It's in another village, try travelling.
c) It's not on this server, check out the LoGD Net link on the login page.
d) Are you sure you didn't just see that feature in a dream?

Here, b) is the correct answer
