Soft factor is set to supplies, but this unit shouldn't be 'in the green'.

Then something happened to prevent it from reflecting correctly in the right hand pane after air supply.
I hadn't noticed a discrepancy between the right hand pane and the soft factor, and I've been playing with air supply since the first version of the game at launch. I didn't go into the unit detail screen and see which one it aligned with. I assumed the right hand pane value to be correct and conducted further air missions with that in mind. When I get to my turns today I'll see if I notice it happening again and get some more details.

I was looking at the right pane details immediately after loading it. Could be something goes off in the middle of the turn. So far I see no discrepancy.
