If you didn't meet Evie and you have seen "someone" at the Bicycle park, check your quests.
I think you will have to talk with Rebecca, and after that, go to the Town's Stairs. You'll see Evie at the right.
ok i edited the save and set q11 new to 1, i get a new tip for rebecca to go to her in the morning, she can't find jimmy(again), so i search for him, go to the bicycle park and again see the girl, yea it's evie, this is where it falls apart, says i need to ask rebecca about her but i never get a prompt when talking to rebecca to ask about the girl! now rebecca's tip is back to continue the prologue! wtf?!? this is similar to what it did before, never got to ask rebecca about the girl cuz it never prompted me and i couldn't ask it on my own just ask what are you doing during morning etc and at evening how are you. WTF?!? is there a way to force evie in?
edit: fucking yeah! i dunno what went wrong but i figured out a fix for me, console and entered q11.actual=3 and bam, town stairs showed up i finally got to finish the jimmy quest. hopefully no more weird things like this. will report.
edit2: finished the game, the only holdup was the evie thing, i have this odd feeling that whatever was in
v0.1.1 Public #Build 1 probably fixed it for others, i was using 0.1.1 public. the ending was funny...
