A quirk or a bug?
I somehow managed to load then lose 0.2 auto-mines somewhere, perhaps I dumped them in the wrong place.
So Earth now has 8.8 auto-mines.
I tell myself, ok no worries, I'll adjust my ongoing order and add +0.2 to "complete back" my current amount.
I did nothing, even when the order was finished. I ended up with 8.8 AM on Earth.
Then I issued a new order, to specifically order 0.2 AM only.
Guess what, no change, the order was finished and I was still with 8.8 AM on Earth.
Check your civ ships and see if the final 0.2 is actually on the way.
I have noticed that sometimes the order "finishes" according to the order list, even though some freighters are still en route.
