Hi there,
See this reddit post: https://www.reddit.com/r/kingdomcome/comments/7xz428/no_fast_travel_events_bug/
Fast travel no longer triggers encounters/events 
After talking to Timmy’s sister, who leads you to Timmy, this bug seems to kick in. I think it has to do with the bandits behind the mill after an intimidating Henry manages to scare them off. They leave saying something like “You haven’t seen the last of us”.
Anyway, this bug removes a great feature of the game. I hope you guys get to fixing his quickly.
Thanks for this great game! 35 hours in and still loving it.
Kind regards,
Vince
