Hello!
I don't remember any similar issue reported by players before.
Do you have any active mods? Perhaps one of them is affecting the world generation.
If you still experience this issue, please send us the last few server logs at this email: support@atomictorch.com
The logs folder location: Documents\AtomicTorchStudio\CryoFall\Logs
(please sort by date, we need only logs with the names containing "Server_")
Regards!
