Apparently this does not trigger response from defense ships. WTF?!
Oddly enough it DOES however (1) trigger a red station box in sector display, (2) does trigger a red sector box in the sector map and eventually will (3) trigger a verbal warning of station attack.
Twice no response by a ship set to defend the complex and I have to quit what I am doing to take over.. sigh.
Pouring over the forum it seems that unless the complex hub is attacked, station defense will stay brain dead.. and that the popular work-arounds are to manually deal with the problem or patrol the system.
My scrappy fleet is representative of my poor starting factory choices.. hehe
- Space Jewelry L
- Soyery L
I've since mutated one into a ADV Sat complex and made an additional complex to produce Soya Husk (so far) from E-Cells.
Anyhow, station defense worked with complexes in X3R as best I can recall.. In any event, in X3TC vanilla it seems this is another long standing bug. Especially if this was actaully the same as in X3R.
I see no solution in the BP so, in vanilla, is this simply:
- manually do complex defense
or
- patrol the sector
or
- hope for the best and let station defense handle it

My fleet is mostly M5 and M4, and eventhough I have a fair number of them I don't really think they're up to patrol duty. I'd think they would do better to stick with complex defense -- 10-15 ships even with IRE/PAC should take care of most small pirate groups that attack the complexes.
It's a bummer that a vanilla *player* needs to divert undivided attention to this task because of the station defense not being suitable/working for complex defense.
Q: Is this problem exist in vanilla X3AP?
