Problems completing converted "Sub Command" campaign missions.
 

I've been unable to complete the very first mission of the Seawolf/688i campaign, even though I have approached both of the destroyers. I believe the trigger may be broken, since I have come within 4 miles of the Arleigh and came to periscope depth (however, the mission fail trigger seems to work just fine, go figure.) In addition, I have been unable to tweak the mission so I can at least skip to the meat of the campaign. Is there a possible fix to this bug?

Depends on what the trigger is in Sub Command that allows the mission to succeed. If it is a 'raise mast' type trigger then you will have to 'fake it', as there is no corresponding trigger in DW.
