This is only a minor bug. A mine did not exploded as quickly as I wanted so I clicked on the mine to set it off manually. Just before I was about to sellect the target ship the mine went off by itself destroying the ship. However, I clicked on space to get rid of the mine selection (that no longer existed) and the game crashed. (i.e. no mine left but I still had the arrow and mini stars for selecting a target.) I was playing TEC. Simple solution is to not do that again:) But I thought you might like to know.
