That’s the result… the first time I opened only 2 orphaned listing were found, but they have nothing inside, are completely empty, no photo, no design, nothing except title. Actually there are at least 56 lost listings… @ilja please say something, is there any way I/we can help you???
If your lost listings weren’t found by the “orphaned listings” repair function, they are not in the database.
But it’s highly unlikely that GarageSale deleted those by itself, because the only code-path that calls delete on entries in the database is the “Empty Trash” command.
My guess is that the listings were never actually written into the database because of an unknown error (bug in the database, problem with the file system, disk way temporarily full), and GarageSale did not report the error.
Can you recall if you listed the items immediately after creating them, or was there some time between creating and listing the missing items?
It’s extremely difficult to remember the precise situation when I created them since it is at least 4 months ago that these 56 (now missing) are running in my shop. It means that these listings must have been relisted at least 3 times, so it means that they disappeared in my database in the last month. So I would say it is impossible to say the exact situation when they were created since they were automatically relisted by GS (when/how… this is not possible to know). If there is something I am totally sure, it is that since January I am not listing new items from zero (except some, but they are not affected) and the running listings are the same as before. Surely the bug must come from some problem in the auto-relisting (I repeat, I am not creating listing since last year for many reasons, so the items were auto-relisted and have been at least for 3-4 times each one). When I created them (so in 2016), I have no doubt, I listed them as soon as after creating (I use one “model”, so I fill title, photos and description and list it immediately, it doubles, the active goes in the correct output folder and I am ready to modify the remaining inactive listing to go on). Is it useful in some way??? I spent more time in looking for bugs then working, and it is a serious problem 
…
I can surely say that this is not the case as many of my missing items were never listed at all but waiting for more items to be added
So do you mean that your orphaned were still inactive??
Yes. There doesn’t seem to be any difference between active or not.
My Lost and Found got 30 listings, only 6 of which were previously listed
Ah I did not understand it!! It is new for me since I only have active and I though it was related to relisting which usually crashes or does strange thing. Very strange… @ilja can the remote debugging help??
But are these empty as mine or are at least your full of data???
Not empty. But… Wow! completely bizarre! I was looking at the list then suddenly one turned blank! It happened right after I emptied my Deleted Items
Lorem ipsum is back 
I just emptied my trash and it deleted something that was not in trash. See above
Curious question, Federico… Do you use one of your listings as the template for another?
Sure Tracy, it’s extremely time saving!! Thanks to the option of “duplicate and move”, I have some “template” listing that I use for specific goods (like one for photos, one for coins and so on). The only thing I have to do is fill title, price, photo and maybe just change some little word in description, then I start it. The active one is sent to the output folder and the original template is still in the same place ready for being used again. Very useful and tidy, so you don’t have hundreds of not started listing every time that you may delete/modify erroneously…
Just a thought, but maybe there could be a connection with missing listings? Maybe there is a glitch where if you delete one, it will also delete the others? Just speculating, I don’t know how it works
I think this may be the only explanation, active listings are moved to trash for mysterious reasons and then we deleted them thinking to empty a trash full of expired…
@ilja GS is the most crashing app I have never met 
every time I leave it running on my computer because I know there are listings to be auto-relisted, I found it crashed and I don’t want to imagine the mess it causes in my database. Maybe all this problems are only related to continuous crashing … hope this will help in some way…
Attempting to relist but apparently my “ended” items are actually active but the active items don’t exist.
They are not in my Lost and Found
With all due respect, GS team, this issue seems a little too serious to have had silence for 9 days.
Updates, theories, insights, speculation or anything at all would be welcome.
