Well I have two bugs I noticed.
1. I extracted and applied @GokUsama most recent language patch which translates every tlq to english.(Great Job )
I followed your instructions as stated and i went into the game and did tlq and adult/master class quest which were translated. Then I went to my namekian character on the same account on the same computer to do the tlq quests and they werent translated! The same thing with my majin character.
2. In the tambourine camp there is a fisher goat. I did his quest and after that when I came back to his original spot, he disappeared. I then deleted the quest thinking he would appear again but he still did not appear.
