For the top and bottom thing, I'll try to reproduce it with an other browser because I do not get it on chrome.
Good idea abt checking the browser. I tried 2 different browsers, Brave and Librewolf.
They both behaved differently than my main firefox. I don't have Chrome.
On most screens, when I transition to the next 'scene' it will initially appear at the bottom
of the page and immediately scroll up to the top. For example. when I transitioned to the going
home scene where I meed the neighbors.
With firefox I was greeted w a lovely picture of the girls butt, and it just stayed like that till I scrolled up.
With Brave and Librewolf it flickered to her butt but immediately zipped up the page to the top.
So, it does seem to be my browser issue. Good call catching that and I'm sorry I didn't check first.
Cheers and Great Luck and Success
