Nope, it was just part of the update to stop gamey scoring. Now when you drop ord or troops they disappear as soon as you start another sortie. Previously they still dropped, meaning you could drop bombs from a lanc, quickly end sortie and up a PT boat, and get the damage points when the bombs hit. The new version fixes that.
But now you have to be careful not to up too quickly after your goon/M3 gets shot down if you released troops.
