While logging-in in my Farmville and Cafe World (both game are from Zynga) i saw a noticed on top of the game windows that the games are experiencing connection problem with Facebook.

Facebook is experiencing performance issues. During this time, farmers may experience lag or lost gifts/bonuses.  

I also notice that i’ve lost some of my gifts when i try to accept them, so it’s advisable not to accept the gift that you received for you Farmville and Cafe world.
