Okay, I just double checked to be sure.
When it comes to the Susan shower scene I'm pretty sure it's fixed. I'm assuming you're loading a save from during Susan's trip. Unfortunately, when you make a save in rpgmaker, it saves the version of the code you're using at that moment. So Even if I update it later, if you're using a save created during the scene the code won't update. You need to load a save from before you go on Susan's trip, or use the skip to day 6 function.
As far as the pool scene goes. Can you describe exactly what you mean? Like does it play the ballbusting animation and everything? I just replayed the scene and it seemed to function like normal. Could you also tell me what choices you made and what fetishes you have disabled? It could be broken with only certain variations.
