so, as it stands now, the tracker has achievements for basically finding a trans/disg, watch someone visit themselves, and watch a player 3 times. i just had a game where i was tracker, and the role list was as follows
vamp
vamp
vamp
vamp
poisoner
hex master (who got necro)
GA
sheriff
amne
amne
spy
tracker
medium
medium
medium
so why not add the achievement "ball and chain" or "lead foot" - track 5 players in a game that dont leave their house? or add both and make lead foot the "track 5 non-leavers" and have ball and chain be "be rb'd 3 times in a game"
