OK, so have attached two lists for you, one is the data from the ignore list, and the other is a report with the available media ids. These look ok, the avialables are newer ids, and the ingores are all older.
But there’s one thing that looks wrong… The ignore list is only 1153 entries. There are 7700 media items, and with only 370 avialables, shouldnt the ignore list be closer to 7300?
I deleted the ignore list, and rebuild the index, comes back with the same amount again.
