There’s a blank tag in the database with ID 1462. It shows up when trying to tag literally any beer containing the letter ‘e’ anywhere in its description. Can also be seen here: https://www.ratebeer.com/Tags/TagView-All.asp?l=e first in the list.
This has been here for probably a year or more now. Since we can’t view a list of beers with this tag it’s impossible to figure out what it was, perhaps it was some word with a diacritic that got lost when you were fixing those character display issues a while back? @joet @services.
Also there are duplicate tags for “oats”. IDs 32 and 1620. I guess the latter can be deleted/merged into the older id as it’s otherwise unusable.
