Thank you for your positive comment!
As for the particular scene you linked to, you're right that that scene is part of the most recent version on Patreon (v0.50), and the public version here is currently v0.4, but the good news is that the next update (v0.60) will be here soon (this weekend), and then I'll also update the public version to v0.50, which contains that scene
Now, as for how you get that scene (in v0.50), it actually shows up on the Mage-storyline. At some point, Sarah will hear a sound in the night, and if she investigates...well, you can explore that when the new version rolls out haha.
