This is what I do. I make the changes (showing the dates I like for each part), I then click save and, very important, I click refresh on the browser page to see the REAL dates. I then do the process over and over until I'm as close to what I'm looking for as possible.
yeah i got my design upgrades.. so basically i think the problem is that these upgrades are given at 13.00 if I add some more desgner later than that even if the date becomes "today" it's going to be delivered tomorrow... am I wrong?
