In online version of the game, my character is full lupine. However when visiting Sam on Gastigoth, either a bug or a typo where it says "You don't have the knot to plug her with". Don't know if it is a bug or if because Sam is currently pregnant
According to the old Flash code, it should be a simple pc.hasKnot(x) check, where x is the index of the cock being used; her being pregnant has nothing to do with it. Are you sure the cock being used in that scene has a knot? If it does, make a post in the Bug Report subforum and attach your save file.
