There's some "invisible" stuff in the game. Like telling the Prototype doll to do a natural stand will cause it to become invisible. You can still click and interact with it, but the model itself just disappear. Same issue with Chamber of lust puzzle, the statue on the west will become invisible when interacted with the "dick" that required to open the room. Another one would be Nurse Candy scene when you got caught sneaking in Guidos basement.
There might be more. And FYI I'm playing the mom route.
I've tried redownloading the full 1.0 ver, tried using 0.52 and then patch it to 1.0, use different link through the patreon post, but issue still persists even when I tried to use the provided full save.
Does anyone else has this issue? Any workaround?
