Well the response and 'solution' I got when I filled out a ticket was this:
This article contains a list of steps you can take in order to retrieve lost inventory. While some of the steps presented may not appear to be relevant to your type of inventory loss, you should read through the entire article and follow all applicable steps. None of the procedures here can damage your inventory, so when in doubt, try them all!
COMMON SOLUTIONS
Clearing Second Life's cache
Second Life uses hard drive space on your computer to store data, including a list of items in your inventory. If this cache becomes corrupted, items in your inventory may erroneously appear to be missing. In many cases, your items are not lost and will reappear after you clear Second Life's cache:
1. Go to Edit > Preferences on the menu bar
2. Click the Network tab
3. Click the Clear Cache button
4. Exit Second Life
5. Log back into Second Life
6. Wait in place for 5 minutes; Second Life needs to reload much of your previously cached information.
Region issues
The Region you are in may be experiencing technical difficulties, especially in high traffic areas. This behavior can prevent you from rezzing items from your inventory. If you are unable to escape to another Region, exit Second Life and log back into a different Region:
1. Go to Edit > Preferences on the menu bar
2. Click the General tab
3. Turn on the option Show Start Location on Login Screen
4. Exit Second Life
5. Launch Second Life, but don't connect yet
6. Enter Sandbox Newcomb, or another known Region name, into Start Location
7. Click Connect
Try to find a Region with a low Traffic score and relatively few objects- such Regions generally experience less strain, and are less likely to exhibit symptoms like inventory loss.
UNSUCCESSFUL RECOVERY EFFORTS
Provide detailed information regarding your loss
If your recovery efforts are unsuccessful, you can provide us with detailed information regarding your loss. For each item you cannot recover, please provide the name of the item, approximate date and time of loss, and the Region where the loss took place. If you do not know all of this information, provide as much of it as you can remember.
The information provided will be submitted for review and help Linden Lab prevent future inventory losses. Linden Lab can not guarantee the replacement or restoration of items that can't be recovered using the steps in this article. >>>We also don’t offer reimbursement for any lost inventory.<<<
Worth nothing in my view.
GOOD LUCK everyone.
