After booting up, I was able to find all duplicate tags with [Data Explorer](https://meta.discourse.org/t/32566?silent=true) plugin:

```plaintext
SELECT name, count(*)
    FROM tags 
    GROUP BY name
     HAVING count(*) > 1

```

For some reasons, there were about **ten** duplicate tags. Wonder why and how those appear there _in the first place_…

Managed to wipe those sucker out, removed the version lock from `yml` file, rebuild, things looks fine now.

Thank you!

👍
