I am having problems with mines as well. I play vasari and the problem was when cleaning a TEC mine field, my scout was in range to reveal the mines but they just kept phasing in and out so when i told my ships to fire at the mines, they phased out so my ships stopped the attack, this happened several times and was really annoying, clear that mine field (10 mines aprox) took me like 20 mins, definitively a mood killer, while having to keep two battles at the same time, one taking another system and the other cleaning one by one those "funny" mines.
Also, i really dont like to see the names of the planets and stars, etc, before i could select the option from the menu and it was fine (show names) but now i deselect it and the names dont go away, or they go away but only on some systems, its so random.
Hope this helps the final version of the expansion to be better, beside those annoying problems, nothing else to report, the new options and feeling of the game are great, keep up the good work guys!!
