Putted a JH in NY to the LSF guard system.
The LSF guard system is already linked to ALaska.
In the ini file, there is a line "goto" that I changed from [NY->LSFGuard JH]-[LSFGuard->NY JH] to [NY->LSFGuard JH]-[LSFGuard->Alaska].
So when you jump in, you will appear at the LSF->Alaska JH, but you would come from NY. Although, If you take the LSF->Alaska JH, you will end up in Alaska.
Me thinks it could be possible to put a JH at one end (entrance) and a Buoy at the other end (exit), So you could get in, but there won't be any other way back.
(I tested and everything was stable, not a single bug)
Its something we can work on for 4.86 I guess. I'll be doing system improvements and upgrades, rather than new ones for 86. You work on changing that 2nd JH to a buoy or invisible object, I'll work on getting random jump holes stable. (They pop you out in random locations in random systems, and you can't go back..)
