Does anyone know how Sea Supply missions work on Tanoa?
On Altis, a small boat arrives and leaves a box on the beach.
Here, a boat comes, but there does not seem to ever be any box left on the beach.
On Altis, the trigger point for the mission is on a beach but here it's usually out on the water.

i read a message on the Community version of Antistasi Tanoa that there should not be a boat but there should be a box left underwater. I swam around quite a bit and never found anything underwater either.

I'm a little confused.

There's also a small bug where if you drown, you don't get the usual option to respawn back at base. You get the "You Died" screen that you usually get in the Bohemia missions and you have to exit the mission because loading a standard save won't help you.
