mrkgnao: No worries. I could easily reconstruct it even if it's lost.
Hope you find the bug.
I think I've got it.
I've pushed another update with the fix.
I've set it so now to send the clear request you have to have turned the checkbox off (rather then when it's already off when you load up the browser), and also fixed another bug that wasn't actually receiving the proper info from the server when the result came back empty.
When you get back to the other computer your wishlist should be saved and if you make an edit it will resync to the server (assuming you update the script first).
Basically the script queries the server for player data, if that's empty it checks the local script storage and it there's nothing there either it creates a fresh profile.
The info from the server only actually overwrites the saved data when a change is made (in which case the new data is saved to be uploaded)
