Devs, AI can not normal move on the surface of USS Freedom or USS Liberty. Variations of problems can be an infinite number. AI does not understand where the doors are and where the walls are, where the surface of the ship is and constantly falls into the sea or passes through the walls, or stuck between partitions!

Some example:

Do anything though, otherwise, player can not use this content for a good singleplayer missions.
As seems to me, pre-prepared routes that will start at the door could be a solution to this problem
