Warp does not work on the server (1.12.2), destination points are created in the core, but the core installation screen does not open at warp. version of the mod More-Planets-1.12.2-2.0.17-GC181 , ExtraPlanets-1.12.2-0.4.5, GalacticraftCore-1.12.2-4.0.1.181, Galacticraft-Planets-1.12.2-4.0.1.181

I will add. If a mod is installed into an existing world, then click + sneak on no one object, but if you delete the world and recreate it, then everything works.

Understood, both hands must be empty ...
