How do I make a character gain sanity when working?

[GRNNOperator]

I plan to have a character who loses hunger when working but gains sanity when working. This is what I tried and it didn't work.
(all of the hunger stuff works fine, just the sanity part doesn't work)
 

local function OnWork(inst, data)
    local burnrate = inst.components.hunger.burnratemodifiers:Get()

    if
        data.action.action == ACTIONS.CHOP
        or data.action.action == ACTIONS.MINE
        or data.action.action == ACTIONS.PICK
        or data.action.action == ACTIONS.HAMMER
        or data.action.action == ACTIONS.DIG
        or data.action.action == ACTIONS.TILL
    then
        if inst._cdtask == nil then
            inst._cdtask = inst:DoTaskInTime(0.3, OnCooldown)
            inst.components.hunger:DoDelta(-1 * burnrate, true)
            inst.components.sanity:DoDelta(1)
        end
    end
end

This code works fine for me. You must be testing a wrong version of the mod, before you added this change. Maybe you forgot to save the file?

That's true actually, I don't know why it didn't work before, but thank you for your help!
