If a Helicopter stands on Carrier Deck, engine off and without crew, the ai in player group is not able to mount by order mount with command menue.
The AI wait for Heli position Z (select 2) is < X.
This is ATL on land and ASL over water.
The dismount works with istouchingground i guess, because it works.
add an OR (||) to the Z coordinate condition with (istouchingground).
thx so far, i expect that with next Update!
