Ended up in war with a faction. Faction attacked my homebase and started sending me "Attacks will not be tolerated" message each time my missile turret hits their ships (long recharge). Singleplayer, so I'm an owner and sole member of my faction.
Expected: Faction not to send such message to someone they are at war with.
Note: faction was attacking almost continuously (ships were arriving faster then turrets could kill them). Yet faction stopped war with me after a day of game being stooped - on load received a message about war end, since "there was no conflict for a while"
