Note that the game was started in around version 1.3.2.3, the bug was also happening in that version and all versions in between.
Bug:
Pirate ships are not attacking my constructors or colony ships. My ships can stop literally right next to a 5 stack fleet and on the pirates turn they will not attack them and just move right pass them as if they aren't there.
-This has happened on several occasions meaning its a pattern of behavior and not a one off fluke
-Difficulty Setting is gifted
-Have not been able to test what happens if my ships have weapons or Armour
-Have not been able to test if the AI opponents also exhibit this behavior
I have a save from when before the pirates move, and after they move and ignore my ships
