Sure, I’ll drop him an email to figure this out 
NB: I got this when I ran the SQL in data explorer
| id | name | topic_count | created_at | updated_at | pm_topic_count | target_tag |
|---|---|---|---|---|---|---|
| 1710 | chronicillness | 2 | 2019-12-03T17:49:17.395Z | 2019-12-03T17:49:17.395Z | 0 | NULL |
will
Tag.find_by(id: 1710).destroy
do the trick?
