Earlier today we added some code to cleanup old unused free-form tags. The goal was to make the lookup in the search field faster and more accurate. Unfortunately the query used was not interpreted in the expected way by MySQL, and this caused a few too many tags to be removed on one of the automatic cleanup passes. Like all the forums (except 1) and just under half the main audio tags. Ouch ...

This has been corrected and a new query that MySQL seems more willing to work with implemented.
