This post contains minor tutorial spoilers, so I am putting obfuscating text here so that said spoilers don't show up on the Discord forum preview. The bugs I have encountered likely don't affect progression, because they're mostly related to flavor text. There is one bug of sorts that may not be linked to the tutorial itself, but I have no way of checking it with a different character because my current characters lack access to the relevant items to reproduce the bug. However, it is reproducible within the tutorial.

The bowl of wax is invisible. Once you pick it up, it cannot be dropped, emptied, put onto a counter, or shown to someone. Also, when the wax stamp is dragged onto the bowl of wax within an inventory, nothing visually happens, and it cannot be used to seal a letter, even if you're next to a candle (I can't recall whether you need a full fire lol)

The book, once opened, is wider than the full screen and the text within it doesn't seem to wrap. I also couldn't figure out how to close the book without restarting the client (but this is clearly related to the book's wideness). I think the book is supposed to have pages (from announcements), but I also can't see the corners to flip the pages/whatever allows for page flipping.

A lot of the cook's items (particularly the ones in the chest) don't have dialogue assigned. The inkwell does have dialogue assigned, but the rabbit seems to think it's food, responding with "Not hungry." (They also respond this way to some other items like the pot, but I do think pots are reasonably associated with food).
