unless it's in the petreon versions then I don't know anything about that.
I scrolled through the comments and the creator said in the patreon version you have to do these things.
1.Talk with the bartender about the cocky guard
2.see the scene on the track with scar and the cocky bandit
3. you then talk with either jester or the bartender I think jester
4.you should be able to sneak in the camp during the day.
(Again only in patreon)
