Was doing some unrelated mod work and discovered that Mission 2 has a strange error or oversight where completing the mission with 0 losses will complete the first medal goal. Normally, you earn this goal by removing all tan mines, but using this instead could probably be faster for some categories, mainly Gold Medal obviously. Data mining console versions reveals they also have this error, so this trick should be possible on all versions. Why this error exists, I don't know. The code is basically in plaintext, so I don't see why if the mission originally had a losses based goal, why they wouldn't just delete that goal instead of making it 0 losses. But whatever. Video proof:
