There is currently a bug where some locations or buttons may occasionally disappear. This seems to be related to the Ren’Py 3D system, which sometimes causes rendering issues. I’m not 100% certain this is the exact cause, but it is my current assumption.
At the moment, the issue is resolved by restarting the game, which refreshes the rendering correctly. A proper fix will likely require a Ren’Py update.
Sorry for the inconvenience, and thank you for your understanding!
