Hey 
I am already in contact with Support but I want to know if I’m the only one.
I woke up with 126 Favorites instead of 5. One more appeared in the last hour, even if I changed my password.
I also have designs in my Showroom Topics disappearing from the selection.
One Topic had 15 designs.
Then I see my showroom displays only 12… and the Topic contains only 3.
Please check and report something similar happening to you
