No gifts opend, from the Spring Bunny
The event did not get extended for two days in my game. I just looked inside, it said the event had ended, and prompted me to open the gifts. I only had collected 40 eggs because I didn't do any crafting. The gifts are in my Gift Box. So, yes, the gifts have been created.
The problem they had was with the recipe ending early so that's why they were extending the event. Again, it didn't extend for me but that's okay. I'm happy with all the freebies, especially the new animals and fuel.
