i checked the generator power source and fixed it and when i got to talk to Bianca to let her know the elevator is fixed it wont let me talk to her i don't know if i'm missing something or its a bug.
BTW, I really like your game :)
Correct you need to progress Willow's event to get into the elevator. However we discovered a bug in v0.13 where if you complete Willows event where you have to guide her around the mall for a bit before doing Bianca's initial quest you can sequence lock.
This bug hasn't been fixed in v0.12 yet. Took quite a while to figure out what was going on.
