I seem to be getting Pirate fleets spawning out of other people's stations. I noticed this while waiting around outside New Maxios, and seeing pirate fleets periodically spawn out of it, spend a short while orbiting it as if preparing for a mission, before suddenly noticing and attacking the smaller Independent shipping orbiting alongside.
These seem to be the relevant lines of the log:
1144895 [Thread-5] INFO data.scripts.world.fleets.SSP_MercAndPirateFleetManager - Checking whether to spawn pirate or merc fleet for market [New Maxios]
1144895 [Thread-5] INFO data.scripts.world.fleets.SSP_MercAndPirateFleetManager - 0 out of a maximum 3 pirate/merc fleets in play for market [New Maxios]
1144900 [Thread-5] INFO data.scripts.world.fleets.SSP_MercAndPirateFleetManager - Spawned pirate fleet [pirate Armada] from market New Maxios
Ctrl+F'd through the log using "Checking whether to spawn pirate or merc fleet for market [" to check, pirates seem to be spawning out of pretty much every station.
