Hey, you're not a new player!
(Ooh, and you're using vi-keys!)
The score system for that bit was added much earlier than the later methods of obtaining prototypes, so it looks possible I didn't centralize the system for awarding points for prototypes (originally there was only one method in the 7DRL--using it, while now we have many). My dev monitor and whatnot are all packed up for
the move tomorrow, so I'll fix this once I get set up on the other side. I'm sure you're correct here, thanks!
