So I am running into a issue when starting a server from the host game screen. If I don't have caves added to a server everything runs fine. If I add caves I get a pop up saying starting the server, generating the world, than I get a screen that tells me dedicated server failed to start. I went digging through the net but have not found any answer to my problem. I also have the server log files attached below. I tried reading through them but everything looked to be running right to me except for a UNKNOWN RESOURCE line. One last thing I have never added a mod, there are no mods on this server or client.
If you have any questions please feel free to leave a post and I will answer as soon as I can.
1. start game 2. host game 3. add caves to a new server 4. start the new server
