The mod script no longer generate Pirates attack the ship version (which begins Barracuda research line) since June month and you will fail (my last attempt). I'm not unlock containment because no aliens appears at all, only mission on shore. May be it was my RNG, but I think game script is bugged now. Infinite infiltration waves of USO's regardless of difficulty, starting from June or Jule. Oh, one important moment for me - my last pirate ship mission fails because Triton get destroyed by HK, while it was on the way to mission. May be it affects or may be not, I don't know.
