Server files are still waiting for approval on curse but the devs posted this on the discord:
https://mediafilez.forgecdn.net/files/5189/561/Server-Files-0.2.53.zip
0.2.53 just dropped for clientside and the devs said the server files are just in approval haha
Seems to be a hotfix for 0.2.52 plus some mod updates. I can keep an eye on it and pop an update here when the server files are live
