The damage for crafted crossbows seems to be broken for Crafting 5, and possibly for all crafting levels unless the progression is supposed to be this flat (why give them different names?)

Here's the result for all crafting levels that let you make a crossbow, all at Level 13:
CR2: 104-184 piercing, no bonus "Homemade Crossbow"
CR3: 104-184 piercing, no bonus "Hand-crafted Crossbow"
CR4: 104-184 piercing, no bonus "Custom Made Crossbow"
CR5: 39-119 piercing + bonus stat "Superior Arbalest"

Here for Bows:
CR1: 72-143 piercing, no bonus "Homemade Shortbow"
CR2: 72-143 piercing, no bonus "Hand-crafted Bow"
CR3: 72-143 piercing, no bonus "Custom-made Bow"
CR4: 72-143 piercing, no bonus "Polished Longbow"
CR5: 93-165 piercing + bonus stat "Superior Longbow"

I'm playing on honour mode so I don't have a save of another level to compare with. Can anyone test and confirm this?
