Hellraiser
Arcane
Restarted factions stop being infiltrated and the Unity wreckage does not show their new locations. Sometimes, the game allows conquerors to track restarted locations but not always.
Good to know, still that needed Kalin to kill me off. Most likely he would delay that at least until he would probe all my tech which I wanted to prevent.
Not seeing new locations via the wreckage is only a slight hindrance, by knowing all the previous locations one can narrow down the restarting location to a few places by eliminating the known ones.
