Should probably ask in game chat instead of making a thread.
VS is unstable being up and down several times a night. I search it every night I play for items I need or can resell at a profit. If it is not working when I log on, I will try it again an hour or so later when I take a break. Sooner or later I will find it working. It is a rare night when it does not work at all. Considering the number of multi page discussions in this forum regarding vendor search I don’t expect the situation regarding it’s being down nightly to change ever. No question that it should work better than it does but does not appear that is going to change.
I am getting so used to it, dissensitised by all the "things that do not work".
