Durability Multiplier not fully working for tools

Under “Combat” in the server options, there is a “Durability Multiplier” option.

This modifier multiplies the rate at which weapons, tools & armour take damage.
Setting this to 0.0 stops weapons & armour from taking durability loss, but tools still lose durability.

Could we get three separate modifier bars, 1 for weapons, 1 for armour and 1 for tools?

Repro steps:

  1. Change Durability Multiplier to 0.0
  2. Harvest stuff.
  3. Realise that tools still take durability damage.
