I've noticed this as a problem with two tags, first 'leaf' always gets translated as 'leaf_(pokemon)' and 'halo' as 'halo_(series)' when the images clearly had nothing to do with Pokemon or Halo.
I know this is more of a minor problem but has anyone noticed any other tags this happens to? It's annoying and if it's happening from our end then I wonder if it can be fixed.
