It might have been said but I wanted to know, does anyone else see a weird favorites section. There are some pictures I have never even seen before in my favorites. And no there is not someone else on this account or something like that.
The migration filled your favorites with all your favorites and all things you voted on, and maybe even cases where you withdrew the favorite/vote afterward.
This could explain either pics you voted on and didn't remember, or pics you may have voted on by accident (and if the last thing I said is true, even realizing it and removing the vote would have had no effect on the migration)
