Alright, everyone just breathe. The way to go about finding a solution is to start with what we know and see what we can learn from a bit of experimentation.
Grappling an existing turbopack into the turboback bay seems, to me, to work fine. However, if I understand the OP, the problem is that there are no turbopacks currently at or near his vessel. So the problem is one of trying to find something within the scenario save file which would make the DG-IV think that it was carrying its usual complement of two turbopacks.
Ok, so I loaded up one of my stock scenarios with a DG-IV that I know had turbopacks in it. Then I saved that as a new scenario save file. Then I released the turbopacks. Then I saved that as a second new scenario save file. Any differences in the scenario files, other than the date should give us a hint.
There is only one line between the two saved scenarios which differs:
Code:
With 2 turbopacks onboard:
But1Cockpit 0 0 0 2 2 2 0 0 0 0 0 0 2 2 2 0 0 0 0 1 1 0
With 0 turbopacks onboard:
But1Cockpit 0 0 0 2 2 2 0 0 0 0 0 0 2 2 2 0 0 0 0 0 0 0
Tada! I'm a frikin' genius! The 20th and 21st digits in this configuration string differ. Hmm... could it be they have something to do with the turbopacks? Well, yea.
Two more saves and we've determined that the 20th digit indicates whether (1) or not (0) there is a turbopack grappled in the Left turbopack bay, and the 21st digit is an indicator for the Right turbopack bay.
I took the scenario with no turbopacks grappled and changed those two digits from 0 to 1, loaded the scenario and (whadda'ya'know) the DG-IV has 2 turbopacks in the bays.
Breathe, experiment, learn as we go... it makes life so much simpler.
