local function OnCooldownTimerFinished(self)
StopAnimation(self:GetParent());
NS.FinishCooldownTimer(self);
end

NS.FinishCooldownTimer = function (self)
NS.RefreshCooldownTimer(self, true);
end

Probably simply the logic if there aren't stacks.

if ( start ~= math.huge ) and ( duration ~= math.huge ) then
        icon.cooldown:SetCooldown(start, duration);
        if icon.Count then
            icon.Count:SetText(stack and "#" or "");
        end
    else

This also needs to check against current time
