Minesweeping is not working with cloaked shpis
 

Just lost an entire fleet in a minefield in spite of the presence of a cloaked minesweeper. No mines were swept at all. Just run a test afterwards and indeed cloaking is the problem which prevented the minesweeping. I don't know if this is intentional and I can very well live with it but is is very inportant for the AI ship designs. Now as far as I know the minesweepers always have a cloaking component in their design which the AI will use, which will result in....

Bang!
