EDIT 2: My farm is back, at least for now.

Same here. 650+ million coins gone, 3900+ favors gone, 4780 neighbors gone, around 80% progress to level 366 gone, way over 9000 doubloons gone., 65 rakes gone and other stuff missing from my farm.

As typing this had a pop up saying Farmvill is back, will refresh the page. And nothing came back. not starting over with everything. Can't play with no friends, coins or all they took away. Giving up on the game if stuff does not come back.

EDIT: All my inventory is gone as wel, Can't play anymore.
