A bug I'm pretty sure I've noticed before 6. 00:
I have a system in my Galaxy overview which is marked with a dark blue dot and a dark blue circle. As far as I know, this means the system contains an uninhabited planet of colony cost less than 2. 0.
Unfortunately, the system in question consists of one sun and fifty asteroids, that's it.
The system might be the one I got the error 3077 message from I posted yesterday, but I am not sure.
Going through the list of asteroids, I might have found the problem, one of them has a gravity of 0. 11 and a temperature of 46. 7 degrees, might this trigger the "good to colonize" routine?
