Same problem here:
==========================================================
[AutoFollow.Events][ChangeMonitor] Profile Loaded: Adventurer - Bounties
Loaded profile Adventurer - Bounties
Game joined, Resetting profile caches
ToggleTargeting, new values: Looting:True LootRadius:50 Combat:True KillRadius:50
Leaving game, reason: Done
Last run acquired 0 gold.
==========================================================
Is this perhaps related to playing a seasons character ?
Because I ran bountyfarm 1 week ago without problems on my regular characters.
EDIT: I copied over the bounties.xml from the zip; reconfigured adventurer to "balanced mats" farm and all is good!
