Sure.
When i load up the preview mode from the editor, or run the mission in single-player the skyhook functions properly. I have the proper add action, I can execute the sky hook and get picked up.
When I run the same mission, exported to the multiplayer, I have no available skyhook action (like the add action is broken) to select.
I am relatively new to scripting, modding and mission building, but I understand the basics and some intermediate stuff. I recently read about server locality and am starting to wonder if that is where the issue lies.
