I'm having same issue, in other places I saw a user ask another person(that had the problem) if they used "Lumiya" at all his answer for his situation was "no". Now in my case I have tried using Lumiya. Though it sucks and I don't plan to use it at all. Though thing is in my SL viewer at home on my PC my outfit/appearnce won't save or save as, it just saves blank. Now what's really weird is, I made an alt account. I tested it on my alt and it saves just fine, while on my main it won't save at all. So I'm left assuming that it's something to do with a setting somewhere or something. Not sure if Lumiya broke my account or what. >.>
