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.
reason is:
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.
Solution:
add an OR (||) to the Z coordinate condition with (istouchingground).
thx so far, i expect that with next Update!
