So the server updated to 5.3 today and also new versions of several mods. Some things may be broken, report your issues here and they might get fixed server-side, but some things might require rebuilding (gold farms).
Nuclear reactors should start now.
My free gold farm and smaller ore farms are completely broken, new mesecons probably works differently, must investigate. I might have to get a real job now.
I hear there are skybox issues, don’t know what. But after returning from space I had a purple sky and
/skybox off fixed it.
