Return to Base trigger
 

Out of steamers, send report; Return to base!

What file holds the trigger to that?
I would like to change that to one, perhaps two. All to often I contact/find a merchant on the return plot to port. The 88 will suffice in many cases, or in fair weather close to friendly shores a contact report on chance my summon an air strike, but if your air support has trouble hitting a barn - might not even show up. I would rather do it submerged.

I think the game trigger for this is zero-torps because you can exit patrol when your out of fish. Or anytime for that matter.

Looking to possibly even add a secondary trigger, one suggesting an alternate before returning to base.
