Chapter 69 - Crash due to missing proc_target when using "weapon trait" items

[SethSR]

This line seems to crash the game if the player uses "weapon trait" generated weapons:

rustrogueliketutorial/chapter-69-mushrooms2/src/melee_combat_system.rs

Line 128 in 33872fe

let effect_target = if weapon_info.proc_target.unwrap() == "Self" {

There doesn't seem to be anywhere that sets the correct proc_target in the generation code:

rustrogueliketutorial/chapter-69-mushrooms2/src/raws/rawmaster.rs

Lines 160 to 186 in 33872fe

	fn build_traited_weapons(&mut self, items_to_build : &[NewMagicItem]) {
	items_to_build.iter().filter(|i| i.bonus > 0).for_each(|nmw| {
	for wt in self.raws.weapon_traits.iter() {
	let mut base_item_copy = self.build_base_magic_item(&nmw);
	if let Some(mut weapon) = base_item_copy.weapon.as_mut() {
	base_item_copy.name = format!("{} {}", wt.name, base_item_copy.name);
	if let Some(base_value) = base_item_copy.base_value.as_mut() {
	*base_value *= 2.0;
	}
	weapon.proc_chance = Some(0.25);
	weapon.proc_effects = Some(wt.effects.clone());
	let real_name = base_item_copy.name.clone();
	self.raws.items.push(base_item_copy);
	self.item_index.insert(real_name.clone(), self.raws.items.len()-1);
	self.raws.spawn_table.push(super::SpawnTableEntry{
	name : real_name.clone(),
	weight : 9 - i32::abs(nmw.bonus),
	min_depth : 2 + i32::abs((nmw.bonus-1)*3),
	max_depth : 100,
	add_map_depth_to_weight : None
	});
	}
	}
	});
	}

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.
