Campaign Crash when selecting TURN>>

I’ve got part way through my first campaign, taken several planets, but cant move any further because each time I press the next turn button the program crashes to a black screen with a message that says ‘close the program or search for reason online’ or something along those lines.

Cadet level campaign.

Is this specific to that campaign? It could be that somehow some corrupt data has made it onto the server in a challenge. If that is the case, it can be proven by starting a new campsign, which should run fine. Is that working?

a new campaign runs fine

this new campaign is working fine and doesnt use non-GSB hulls, the campaign with the corruption uses the steel dragon hull so maybe thats the problem. anyways ive deleted the old campaign.
