Please do not download the file unless you want to host it again (or unless you are a Dev and willing to fix the bug ). It's limited to 10 downloads and I do not have time to waste on submitting another zillion accounts on filesharing sites and have my mail acc spammed later on.

Anyway, to witness the bug, please download the file (sorry for the whopping 10megs, it's the 14'th or so hour of a huge map game. The bug occured a few times before, but only yesterday have I found this subforum and decided to submit this save ;s) and try this:
- double tap 1 key, it will focus on my Marauder flagship near planet Peleus.
- order it to use Stabilise Phase space
- Order the rest of the fleet near him (without the marauder of course) to attempt a phase jump anywhere there is a phase stabiliser node present.

You will notice they turn around and attempt to jump to the nearby asteroid Cerebriones first, and then use its phase node, as if the marauder didn't even exist. Notice that they are also willing to jump from Cerebriones to planet Minox, which has my stabiliser built but which is no longer mine due to having been ravaged by one of 4 AIs raiding me. It all DID work a number of times before, as the Marauder was my first cap ship in this game (so it has served me well with its stabilise ability a few dozen times over the past 10 hours!).
This bug has occured in many ways:
- Ships refused to use a newly built stabiliser. More often though, they have no objections. Dunno wth.
- Ships refused to jump into a planet which is mine and has a stabiliser, but is under attack (the stabiliser itself is not though). Again, they usually do it as they should, so no idea here as well.

One clue about this bug is that at least twice (again, not always) it occured when a ship tried jumping from/to a planet that changed hands. Peleus was another AI's world for instance, then I took it over, had to sacrifice it later to defend my inner planets instead and retook it now after a few hours of AI's occupation.

Still, I could not come with any kind of solution, fix or idea what was going on.
I successfully warped my fleets all over this system in both directions between any two of the following:
- my world with a stabiliser node
- a neutral world with my stabiliser node (used-to-be mine, but bombarded into neutrality)
- a marauder-placed node in my/neutral/enemy territory
