Campaign slowdown & submarine missions

[BrettMRC]

I've noticed in the last version that campaign turns have slowed excessively once you are 2-3 years into a campaign.

Sometimes the next turn will not load, and you are left hanging in the screen while nothing happens.  (Although you can save, exit and reload still)

The same thing happens 3/10 times when doing submarine battles, you hit "auto" but nothing happens and you cannot exit the window. (Although, as above you can still access the save menu, then leave and reload the campaign)

If you reload the campaign, in both issues it will then move past the hang up.

 

Anyone else experiencing this?
