Wigfrid gains very little inspiration on a beefalo.

This is less a bug, and more an oversight, but I thought this fits here.
 

Wigfrid's inspiration gain uses the base damage of her weapon in hand(or default damage) to determine her inspiration rate each hit. However, when attacking on a beefalo, the base damage is calculated as her default damage instead of the beefalos damage, this makes it very hard to gain inspiration when attacking on a beefalo as Wigfrid.

 

local mount = self.inst.components.rider:GetMount()
local player_damage = (data.weapon ~= nil and data.weapon.components.weapon:GetDamage(self.inst, target))
	or (mount ~= nil and mount.components.combat.defaultdamage)
            or self.inst.components.combat.defaultdamage

Changing lines 118-119 in components/singinginspiration.lua to this could work to make the inspiration gain rate calculated with the beefalos damage if the player is riding one.
