After wasting an hour last night trying to relist auction items in store inventory format eBay's own relist tools flagged errors and said the highlighted items needed fixing. But it would not actually display the items it claimed to highlight and would not continue either.
Attrocious software by eBay (and people moan about M$), I looked at the saved listings today within Auctiva and at least Auctiva warns me about category deprecation. Low and behold all non-fiction books are now under non-fiction ( I was aware of the aggro on eBay's forums about fiction) did not realise non-fiction had been nobbled too.
Unfortunately I now have to change all listings individually, at least thanks to Auctiva for flagging up what the problems are
, eBay 
(glad your profits are up again 
).Trying to pre-empt this on magazines by selecting a level which is not aleaf category is not possible either , groan
So before they (eBay) do the same to many other categories (I understand they will wreck the most succesful first and work down), please CEO Jeff lets have the ability to bulk edit the eBay category before large sellers with stores go insane editing hundreds of items individually.
There is no point in asking eBay anything except take my money
