Not sure if it’s just me but ever since the new update, when I try to put a model off-sale, it says "Your changes to the item have been saved. " but it didn’t really go off-sale. 
I tried using other browsers but it still won’t work.
Link to model…? (It can’t be fixed if you don’t tell anyone which model’s settings are broken)
[strike]I think it’s just me[/strike], but I can’t put ANY model off sale after yesterday’s update.
Same – can’t take models off-sale. Tested on this model.
