The last patch broke the Gallery. Upon opening the Gallery everything is fine. The menu is the same, it shows the Households, Lots, Rooms, and Tattoos according to default filter settings. However. Upon closing then reopening the Gallery, or simply changing a filter, the Gallery will delete/hide Lots. Even Lots that are saved in My Library are effected by this.
This happens regardless of Mods/CC. I've tested with, and without Mods/CC. Both cause the same effect.
Chance of this happening is 100%. I've tried 10 times, and all 10 attempts have had the same issue, WITH THE SAME LOTS.
However. If you click on one of the Lots that WILL be deleted/hidden, you can view it, and even place it with zero issues. Upon reopening the Gallery though, the SAME LOT YOU JUST PLACED will be deleted/hidden, and you will never find it again.
