Keg Brawl Super Throw
It’s not a bug. You can throw it that far using the ‘2’ skill (Lob). You need to look up when doing it though or else it doesn’t work and you throw the keg on the ground right in front of you.
To me that seems rather… cheap… of an tatic (if you can even call it that), throw it right under your score keeper from mid-ground or 25% into enemy territory and thats an instant score.
