All The Nodes

There is a known bug where if there is an active compacting field and the server is restarted the server crashes on startup. To fix this crash, remove the compacting crafting and the compact machine from the server mods folder, start the server, wait for it to start and then stop it and re-add the two mods. This will allow you to re-enter your world without losing it.
It is recommended to make backups frequently
