My guess is this gets fixed in a later chapter, but it would be nice if that was mentioned here. If this wasn't intentional, I think either adding something like weapon.proc_target = Some("Target".to_string()); to rawmaster.rs or changing the line in melee_combat_system.rs to use unwrap_or_default() would fix this.
This line seems to crash the game if the player uses "weapon trait" generated weapons: https://github.com/amethyst/rustrogueliketutorial/blob/33872fe582f226178436847e1f74eafcbf9c0d1a/chapter-69-mushrooms2/src/melee_combat_system.rs#L128
There doesn't seem to be anywhere that sets the correct
proc_targetin the generation code: https://github.com/amethyst/rustrogueliketutorial/blob/33872fe582f226178436847e1f74eafcbf9c0d1a/chapter-69-mushrooms2/src/raws/rawmaster.rs#L160-L186My guess is this gets fixed in a later chapter, but it would be nice if that was mentioned here.
