Oh something definitely broke there. Does the pattern move away from the skirt when you cancel and re-accept the client? And it doesn't let you finish, right?
Did you do anything special before accepting that client? How many times would you say that the random clients wouldn't accept your request, despite matching it perfectly?
Do you think you can upload your save file so I can check it out? The file should be located in your Tailor Tales > www > save folder and called "file1.rpgsave" if you could upload that to for example dropbox and send me the link, that'd be great!
