bend_r scratch that, Earth and Luna are not in there and don't have to be.
I did some more research, this same issue is reported on other packs (E2E, FTB Continuum) when using SpongeForge.
Are you using Sponge?
TBH at this point a world download would be OK for me, later in the pack you are basically required to use RFTools Dimensions and since those are banned on your servers I would want to continue in SP anyway.
