This is probably going to be said as a repost but again, i saw no thread. This is a uselss exploit, but still pretty fun. I figured out if you accept the quest where you go into org IF and holler for a brewery, if you abandon you still have the mount. I don't know if this could be used in sync with the "get the portable barrel, turn in get 2 tokens repeat" but it may.
Just a fun exploit.
