Ok, so here are the steps I've taken:
1. Connected to the server, Logged In, ... It's working.
2. Connected via Feudal Tools
3. Uploaded Terrain Files as instructed
4. Selected Custom Map and Deployed
5. Changed the animals and day cycle time as instructed
6. Restarted the server
7. The server showed it was online.
8. Stopped server and changed back the animals and day cycle time.
9. Deleted the nm1.nmesh file as instructed
10. Restarted the server

It began to create a new nmesh file, but only is 40Bytes in size... previous was 104.67MiB and the server continually shows as offline. Please advise

It is finally showing up and feudal tools connects flawlessly. Now I have a bigger problem...
Every time I try to connect to it in-game I get the following message:

"The server has terminated the connection: Kick reason: CRC check failed. Repair needed"

I've done the steam repair/verify files, but no clue how to resolve this.
