I too have had this problem, I had a commerce raider, I found it by sailing in the direction I placed it and there it was just sat there, I had another ship come sail in it's path, I thought it might start to move once it detected the other ship but it didn't.
When the other ship fired, it returned fire but still didn't move, it would have been nice to see it perhaps try evasive action, funny thing was they sank each other.
