What I was doing was getting my ships out to sea at about 5 knts, the choppers were patrolling ahead while the Nimrod was dropping sonobouys out the yin yang...
At one point I had enough bouys out that I wanted to go 'active' for a bit so I could turn my SSBN north in that direction.
Crash one..

Ok Screenshot done and hit cancel and continue....I think I was able to get the sonar active. Moved to the next ship and repeat..
Crash two...

Exited the game and got this....

Scenario one had NO issues.....[:)]
