It's been a month since my inventory disappeared. I tried everything I could think of to fix my inventory and even submitted a ticket on the SL website, but nothing worked and no one replied. I'm close to accepting that my inventory will not be fixed. Sure, I'm upset that I spent a lot time building, sorting, and spending L$ on my inventory and there's some things in there that I'll miss, but I'm more upset that I didn't receive any help from the SL customer service.
I've been spending less time in SL because I couldn't do much without crashing. I have alts that I can use, but it just isn't the same as using my main account. I used to not like the idea of the new display names feature, but now I'm looking forward to it. Once that feature is released into the main viewer, I'm going to create a new avatar and will change the display name to katfancy Kiergarten. It will kind of feel like I'm still using my original avatar, but with a fixed inventory.
