I double-checked, and in version 0.975 that scene wasn't added yet, so you were playing a version of 0.976 somebody leaked. At least that means there are no bugs, it's just where the content ends.
Not possible with the version of RPG Maker I am using, sadly. Blame it on my lack of funds when I first started.
It changes a few things later on. This is a list of content tied to either completing the quest, meeting someone there, find a secret, etc.:
- If you get enslaved later on, you can be bought by a different owner (you meet her during the party, and she takes an interest in you). This is only important if you are interested in the ponygirl path;
- You can meet a young noble (he is the nephew of the host), and depending on how you interact with him, he might be infatuated with you later on when you see each other again (more noticeable during your own party, if you speak to him);
- You can find a VIP pass for the Queen of Hearts in Tarkas (there is an alternative way to earn one later on, if you miss this);
- There is a mini side-quest you can take on for your Masters if you are a cowgirl (it improves your "fame" within the faction, although currently that doesn't mean much).
I *think* that's all for the main stuff.
