Hosting/Running COOP Missions in Lobby Mode

[Klink-257th]

Looking for straight forward "how to" instructions. Would like to create missions, or download missions (like from missions4today in IL2 1946) and run them in COOP mode either through lobby or as server/direct connect.

Problem currently encountering is only host is seeing the aircraft in launching a COOP mission ... client sees only mission objects (like ships). How is client suppose to get into an airplane? Note, we don't have this problem if launching a dogfight mission.

Thanks in advance for your help.
