/fe now links to fox ears, but before that the autocomplete shows all other still-existing shortcut aliases, which are /fe1, /fe2, [...], which take precedence over fox ears due to them being aliases. This causes fox ears to not pop up at all in the autocomplete, which could cause confusion.
Dragon Ball has a similar issue, albeit not as much. The first result by typing /db is the /dbgt alias, but there's nothing past that.
I personally wouldn't be against removing them since they cause bloat, but some game's names are a bit of a mouthful, and i can see why someone would keep them. Maybe making them not pop up on the autocomplete would be an option?
