As the launch/recover button is absent, what shall I do if I have, let's say 20 mines in a planet cargo and I want to launch only 10 ? (without using a mine layer of course !)

Same pb with fighters, satellites...

It's launch all or launch nothing I'm afraid.

Also, if the amount of units in cargo exceeds the total amount you can launch in one turn, the computer decides which ones get launched and which ones stay aboard according to it's own infernal logic.

Short of a hardcode change from Malfador, there is nothing we can do about either of these things
