The way Ren'py works is that there's no individual user bugs unless someone's been manually digging into the code and altering variables. If something's broken, it's broken for everyone.
To get Emma out of her room you need to have Claire in the Manor. Then simply go to Emma's door during the afternoon and watch the event. You have to do this a few times! Eventually she'll open the door.
If you have Claire, and you've seen the event at Emma's door multiple times, and you're stuck in some kind of loop, let me know exactly where you're looping and I'll dig into the code to see if something's gone screwy.

I have Claire, annoying little snot nosed blonde brat. I visited Emma multiple times for, gosh maybe a weeks worth “in game days”. Nothing, Emma would do her usual cute stammering for the MC to go away.
Now, I managed to get past it finally. Not sure how or why. But suddenly it just randomly started going through. It was nice to see the brats softer “sisterly” side.
And here I was worried I would have had to dump my save and restart fresh.
