+1 - same problem here, wanted to restore a disenchanted item. The restoration page only shows items that I vendored or destroyed. None of the many items I disenchanted over the past weeks are listed for restoration.
This issue really needs to be addressed. A service is offered here that specifically states that “sold, destroyed or disenchanted items can be restored using the Item Restoration Page”.
… nothing has happened over the two months since this thread has been opened…
Hope this will finally be fixed soon.
