I get the occasional null reference error when I try to access one of my fleets. In the past, I would save the game, exit, and relaunch. While this works, I found a much simpler solution: Simply, wait! Check something else and then come back to your fleet. Most of the time, the null reference error is resolved!



My theory is the AI routines are accessing my fleet when I try to open it. Once the AI is through, everything works as it should.



I have only recently discovered this, and I have only tried this in a co-op private game. I don't play solo much anymore, so I'd be curious to hear if this works there too.
