I tried to upload or embed a couple of small photos to this reply, but to no avail. I can send them as an e-mail attachment if you can provide an e-mail address.
In the meantime, the HQ is currently sitting on Stockholm with the fighter on the adjacent hex to the NE (i.e., the hex north of the port). There is also one Swedish corps in the woods hex immediately to the SW.
I can confirm the units are attached by Auto-Assist to the HQ (e.g., when I click the HQ and hover over the units I am asked if I want to "detach").
Both Stockholm and the adjacent port are at level 5 supply. Rather oddly, however, when I use the check supply function, the Stockholm hex with the the HQ is showing "9" while the hex with the fighter is only showing "7" and the other four adjacent hexes (including the one with the corps) are showing "8" supply.
If you want to check the actual game, it is the game MJY versus Hartmann301. It has been like this for several turns, so I assume you could check the file at any time.
