Watchful seems to work for me. I think it only works for actual fleets though, which might be considered a bug.
That masscap bonus still works for some reason, though I have no idea how.
Hi, you mentioned the masscap bonus works for you, here are a few threads reporting the bug
(this one includes text of the event which shows the error, targeting the faction rather than ship, which is still present in my files)
The event still doesn't work for me as of the latest version of the game (just had it go off last game I played and I chose it to try, and it didn't work again).
Also you mentioned watchful works for you? Can you explain how it works? I've tested it pretty thoroughly and couldn't see any results even with ships directly beside my planets. The Perk itself implies that every ship should receive a free escort fighter while in our 'Zone of Control' some take that to mean influence, others think it means something else (some sort of arbitrary hex radius of a planet i believe). In any case I've never gotten it to work, can you confirm?
