Those settings are applied to ALL groups at scenario start, rather than as they arrive - the global setting is not persistent.
I would need a in-turn save to try anything
AH - that explains it! Once Player 1 makes an error with those settings, it's a real pain because Player 2 (and Player 1 if he wanted it differently) have to vet each unit as it arrives. Here's an idea in the hope that it's practical and not much trouble.
There are currently displays for "all air units" (the "A" key) and "all ground units" (the "G" key). Air units arriving on ship are really not an issue in my experience, but there is the "N" key too ("all air units on ships"). Could those displays have a toggle added so they show either "active" (units in play) or "inactive" (units yet to arrive)? The player would then be able to, for example, call up the "all air units" display, switch to "inactive", and change the aircraft replacement setting for all units, the pilot replacement setting for all units, etc.
What do you think?
