Cone Sector's boundary is permit locked; however the interior was not as of pre 3.2; Gnosis can essentially jump through the 'locked' zone either side of the permit barrier allowing access into the inner region. Commanders can't because nothing else has sufficient range from a single jump perspective.
To be fair, Gnosis isn't even "jumping" from a game perspective anyway; it's being relocated between two systems by Frontier. To "emulate" the jump it would make, if it actually could do such a thing. There is no other way in, or out (that is known).
If Frontier have gone on to lock the entirety of the sector, not just the boundary into it, then that's actually hilarious.
edit: they've locked most of the Cone Sector. AHAHAHAHA.. oh god my sides, let me know when Q4 update drops - best of luck everyone. o/
They probably looked where my ship currently is & said
'....Hey, this CMDR's near to finding a 'legitimate' route to the Cone Sector, LOCK IT OFF, LOCK IT OFF!!!....'
Added.
On saying that, I'm now intrigued!
For FD to suddenly 'lock off' the Cone region & the nearby 2Mass region as well....what's going on? Why have FD locked it all off?
Last time that happened to me I was landed on a planet in HIP 22460, when it got locked off, now there's a Megaship in there.
Update 3.2 brought me absolutely ZERO stuff that interests me in the slightest.
My dilemma now is..
Do I park up & put the game to bed until Q4?
or
Dock at the Gnosis & see what FD's up to? - all the time knowing it's likely to be nothing!
