I have spent a lot of time on a special listing on THURSDAY nights, too.
Only to loose my work.
It can be like a pop to the head, that does hurt. Can cause a awful feeling deep inside somewhere near your stomach.
Usually the problem I had was that AUCTIVA was updating their program on Thursday nights at 10 pm Pacific Time Zone.
I was having so much fun making this listing, I did not notice the time was now 10:03 pm, pacific time, on a Thursday night.
ALL is gone. Sometimes, if it is a couple minutes after 10pm you cannot even SAVE any of the new listing you have worked a long time on.
eBay also updates on Thursday nights at 10 pm Pacific Time zone.
I have solved this situation via making Thursday night after 9pm, MY FREE night, MY free time every week.
Today, this week, like many of the previous recent weeks, I have free time on Thursday nights.
A Free Time is good for a soul.
