Ahoy All!
I'm sorry if this has been asked before. But I am trying my hand at mission editing. The first thing I wanted to attempt is to allow myself to select different sub classes for the submarine school missions. However, I can't seem to figure out how that is done. I looked at the other missions where the sub class is selectable, and there doesn't seem to be anything different.
I know I must be missing something.
I read some article about the date, but I changed the mission start date to 1945, and still, only Porpoise is selectable. Please help!
