I'm still learning the mission editor and I read the tutorial but I am having trouble having enemy ships show. I want to have several enemy ships so that I can practice with the torpedoes. I know that the entry date and the start of the mission date have to be exact so I set the enemy ships to that. I validate the mission and it is fine but when I launch the mission, only I spawn and no enemies do. I've attached a screenshot of what the enemy ships look like.
