I could be wrong but I don't think the trigger (SSN Enters New Zealand Territorial Waters) that starts the event that teleports the sub is set up correctly, it looks like the trigger will only go off when the sub enters the area off New Zealand, but it won't ever do that BEFORE the event. Thus it never teleports. Specifically the trigger is set to "Unit Enters Area" with the area defined by rp-480 to rp-483, but the unit isn't going to enter that area so it never goes off. It should probably be a "Random Time" trigger.

I just finished this, and after expending several thousand sonobuoys nothing happened. No US sub showed up, or snuck into one of the ports. I loaded the save game in the editor and the sub is off the Ivory Coast and the mission it is assigned to is inactive, I'm guessing this was supposed to teleport somewhere but didnt, or perhaps this is intended and there is some random chance that it was all a bluff? Does New Zealand buy its sonobuoys from the US by any chance?

Oh, and "chose to engage" at the end should be "choose to engage"

Noticed the side briefing contains a typo, "B. ENEMEY" should be "B. ENEMY"

yes well trump would violate our nuclear free zone
