Not sure if this was mentioned, but I thought I'd bring it up.
map: Triumvirate
phase node generators: Antorak class Marauder lvl 7 w/ phase stabilizer researched. Other, Kostura Cannon
I guess I normally win/lose a match before I build any cannons, but I did want to try to use the cannon's phase stabilizer option on the victim's planet.
situation: While on the offense against the AI's home system I decided to save time and go for their homeworld. I did take over one planet and fired the cannon on theirs which was 4 jumps away. I saw my shot hit, the node was active, I activated the node from the marauder, the planet that my fleet was at said the node was active, but the path was set for the 4 jump instead of the direct route.
Is this done on purpose so that the Vasari need a physical phase stabilizer at the planet such as a gate or Orkulus starbase to use the artifical ones? I still have the game saved, so I'll build a gate and see what happens.
Here's the images below. You can see that the nodes are active. My guess is that it would give the Vasari an unfair offensive advantage over the other races.



edit: I tested with a Phase Stabilizer built at Enid, it didn't work either. I don't think the node that the cannon creates works correctly.
