That scene works for me too. You might try downloading again, maybe your download was corrupted somehow.
I've also encouraged DS to make the ipatch so that it is always on, as long as the patch is in the "game" folder. Ultimately it is up to him though since he's the developer of the ipatch. The ipatch needs to be made by a 3rd party developer so that I don't get shut down by Patreon again. When I write the game, I write it from an incest patch is on perspective. I then write the safe for patreon non incest replacement lines, and send them both to DS. I then delete the incest content in the script and DS takes care of the rest.
