I was unable to jump to Cecees (as per post #36) even from an outside system - I always ended at the "underneath" star. I tried typing the name into the GalMap, which selected it and set it as destination but the game would still display the system info for Esusale and only jump there.Thanks @Arioch. On those star systems that appear close enough each other (making it impossible to make a jump between them directly). There are similar issue in Elite Plus too. That's probably because star chart isn't 2-dimensional, all systems have 3 coordinates. If X and Y are close enough to mark same spot, Z still differs. If systems A and B are close enough not to allow direct jump, going via C allows jump to either system. Can't recall how it is exactly in Elite Plus, but I think there must be at least 0.8ly between systems to allow direct jump. Shorter than that and galactic navigation chart cannot make difference between systems if being either of those.
It think this feature is present in every version of Classical Elite.
An unreachable system, hidden in plain sight. I'm sure it's a total coincidence that Cecees has exactly the same amount of letters as Raxxla...
