I've gone up as far as I can go above the EAFOTS settlements without Jumponium (About 250LY) and not found any earth likes at the moment. I highly doubt I should need to use Jumponium to find beacons, but it is worth noting that there are a lot of G class stars in the EAFOTS sector about 700-750LY up, which are entirely unreachable.
I'm going to hang around this level as there are a few stars up here to investigate, but I suspect our beacons and content are not up quite this high.
Next I'm going to try drawing a line from the EAFOTS bases and follow it up as far as I can. I think that will end up back in Myoidee before I run out of stars.
I'm thinking that everything should be within 200LY of the bases tbh, as that's the area we were given to investigate in the CG, and the bases themselves are really close together by that comparison.
I'm doing the total opposite of you, I'm 1300LY below the abandoned settlements, I'm starting to come across newly discovered Neutron stars down here. I started focusing on these as I thought one of the expeditions last report was from a Neutron star, so thought it was a clue, but then realised it was from the conflux expedition.
When does 2.3 go live? I'm slightly worried that new content and discoveries will occur in the Pleiades, I just hope the Formidine Rift isn't overlooked on the next release.
