Here are some errors I found: Extimated->Estimated, desrepair->disrepair, and I don't understand this sentence, "...explain to you your mansions." Maybe you meant, "...tell you more about the mansion." or "...show to you your room." or something like that. Chimney->Fireplace, "...to no avail."->"...but to no avail"
Sorry for the late reply ;w; the message got somewhat buried in the notifications.
Btw I tried it and I can't trigger the error, I think I missed something. Does a code\text of error appear? Which items do you have in the inventory? (So I can collect them and try the same route as yours to trigger the error) Again, thank you for your patience ;w;
