I am up to 2/44 and have 5 AKE's with this problem. It has occurred when trying to reload large bombardment task forces. Not sure what to do with the ships. I did try to get them to unload in a small port with no success and now I am sending them to Sydney to see if that makes a difference.
Thinking about what I did in Darwin, and including Don's comments about the logic, what I think happened was I got down to zero fuel in Darwin at a point I needed to send out a combat TF, so I "robbed" a transport TF in port of fuel by using the Replenish at Sea button. That got me fuel, but it might also have pulled the organic supplies in the AE down below zero rather than "pulling supplies through the AE" from the port supply. I tend to think of Replenish as being fuel, but it's ammo too. I think that causes the supply variable in the AE to wrap around somehow as any time you get a value near 64k in an 8-bit variable it's pretty suspicious. Even more when it's negative.
Without checking, I also think the various AE/AKE models, both factory-made and conversions, have supply capacities ranging from the low 2000s up to over 8000. This makes it very easy to pull the smaller guys dry if you forget and Replenish at Sea. I think.
I'll take a couple of my bugged guys and try a big port. I've tried to unload the supplies and that hasn't worked. I'll see if any will load resources or oil too, and free up.
