The save point kinda glitches out when you enter the bridge puzzle room where Sans first tells you "you're gonna have a bad time. " by displaying " That comedian... " instead of the actual Snowdin kill counter. You probably should've kept killing everyone else in Snowdin Forest until a "But nobody came..." shows up.

You can still redeem your Genocide Route, if haven't entered Waterfall, by going back and killing whatever's left. It is possible to do the Genocide Route and only battle Neutral Papyrus.
