Did you know that buying an item set to 'buy object' with 'show in search' selected, deselects 'show in search' when purchased, so every product bought needs to be reset after it is bought.
That's a bit long winded, but it's late.
I've tested this, and would be interested if someone else can look at their products which have recently been purchased too.
Anyway whatever I made a JIRA report
