I have played a couple games with 1.6.1 and I occasionally find that constructors stop showing their range grid. It is not a huge problem as it seems to go away by saving and restarting the game and reloading.
However, because of this submitting a save game seems pointless. I also note that attempting to use the support tool seems to work but it never finishes. Is it supposed to take more than 10 minutes or so?
I am wondering whether anyone else has seen this or whether it has been noticed by SD.
Thanks.
