I need prolong the German battleship activity for compensate for fools day server update

Because of the fools day server update use 1 hour , I can not play for 1 hour today and I got only 730000 points until the end of battleship activity . I think many people have same issue . I think its necessary that give us more time to finish the activity , just for indemnify for fools day server update.

Are you absolutely sure it was still possible to gain score for coupon upgrade?

AFAIK time aviable to grind the upgrade is tied to last star and that ended few days ago.
