Sets value on a nil lasknown

fixes #1215

lastknown is not a clone of the footprint, so this code is kinda dangerous. It'd be better to do this:

if self.lastknown then
    fp.x = self.lastknown.x
    fp.y = self.lastknown.y
end

that spawns the player behind the statue, and i'm not sure why its different

the reason i changed so much was the spacing was off and that bugged me
