This trips players up from time to time, but the button to use the stairs is on the sidebar on the left. Step onto the stairs tile on the map, and you should be able to use the stairs button.
Thank you for this! I was able to find a second bug with the button (a preg jumper has a 1 in 8 chance of showing a scene, but blocked the button every time with or without a scene). Next patch should fix both issues.
The only requirement for the button to appear is that flags.TESSA_REVERIE_ACCEPT is set (well, and that you haven't already finished the quest.)
If you clicked "I'm in" then that is set. If anyone has a save to share from Urbolg's tile with the issue that would be great. I can see how there...
Progressed further and I do seem to get the later button:
edit: possibly Urbolg is interfering with this, share screenshots if you can. I'll share a possible fix with the team.
Very weird. I have not done this content myself, but adding her panties is enough to unlock the button and map icon on my machine:
edit: ahh, looking at the wrong button the entire time. Nice donk.
Can you share your save and some more info on the crash message?
edit: ahh, evening is in this scene. It's quite likely the crash for her bust that's in this version. Hopefully we can get a patch out.
The room should say Treasure Nova’s lounge is a smokier part of the casino, muggy with the scent of sex.
For the button to appear, you must have her panties, have done the ZS probe, and be a backer. Let me know if that helps.
