Uh, I added $ char.set_flag("_day_countdown_interactions_blowoff", 2) to kiss refusing and proceed to the city. After every refusing scene I got
File "game/library/screens/locations/cemetery.rpy", line 25, in script call
$ gm.start_gm(result[1])
File "game/library/interactions/GM - greetings.rpy", line 861, in script
$ renpy.show_screen(exit)
File "game/library/interactions/GM - greetings.rpy", line 861, in <module>
$ renpy.show_screen(exit)
Exception: Screen graveyard_town is not known.
Then I went to the tavern and initiated a GM outside of it. I got
File "game/library/interactions/pyt - screens - interactions.rpy", line 42, in script
show expression gm.bg_cache
Exception: Image 'bg tavern_town' not found.
even before the kiss.
But everything worked perfectly at the beach.
Something is clearly broken now
Besides, the flag doesn't have any effect on interactions with hired one, I don't think it's a right thing to do, unless they are slaves.
