So I was testing sins on a network.
Just when I was about to end the game (after playing for a few hours)....
I got this:

See the
-1 on the
Crystal? The Game locked up, and when I went to exit out of the game on the laptop, it too had locked up, so I had to fiddle with the key's to try and get out of it, eventually I did.
It happened when I was upgrading the fleet size (probably from the 5th buttons from the left).
I did get a different error on my laptop too, I was trying to get a pic of it but it closed too soon, something about Microsoft C++ Run time Error.....
v1.05 worked fine, but the v1.09 beta gave me this error.
