In the Guide under Contract I think it is supposed to say Jewelry but the second L is missing. So you unfortunate misspelling :c
the source image is probably came from version 0.3 or 0.4 so it's very early. and the creator of this game so he probably ignored it
Welp. That a mistake on my part. I’ll update the picture in the next patch (also contract system has changed a bit so I will need to update it anyway).
