I have had this happen a couple of times on this account, where i find i've lost auctions in much the same way as the mysterious phenomena of sacrificing a sock to the washing machine XD
More recently though i've found a strange reversal of having my lot number go up.
I have everything set to 3day runs with 10 relists so they show up as ending soon more often rather than languishing in the depths of the searches etc.
Every so often i will login, go to the unsold section and relist. I then go back to the unsold section where everything now only has the option of delete (because its already been relisted) then by chance i have logged in a few days later and found items i relisted (and then deleted) which seem to be running as duplicates.
All of my items are one-offs as this is a personal account clearing years worth of 'stuff' from family, thus ruling out the issue where multiples are listed and 1 sells. So if items only show up in the unsold list when they have finished without selling and i only relist from there, which upon doing so only then allows them to be deleted, how are they duplicating? It's not even as though the system has glitched and listed twice when i hit the button, because generally the items show as finishing days apart.
Look out people eBid listings are either mating and reproducing OR they are disguising themselves as other listings in a bid for higher visibility and then having forged a German passport they will be off *whistling great escape theme*
Have a good day all
