Does it work when your worker has +3 extra work done for timber,ore,fish,etc. packing? I'm getting 50/50 results of yes and no via google. No +3 skill=worker only uses 5 of each material / with +3 skill=worker uses 20 of each material, in my mind thrifty works with a worker that has +3 skill
#Thrifty worker skill
half badger
wispy prairie
10% chance to proc
Proc = 10% of 1 crafting item is returned
So for crafting like Plywood x5, worker will need 50x Planks
With 10% proc you will get 5 plants back in storage
If material needed for craft is less than 10, then 10% of that material is 1
And if needed material is 5, then 10% of that is 0.5, which is nothing and game will not pull material out of air
