Remembering tags after quitting the world

[Residays]

So my mod adds tags to prods when they are being built via a function.

local function OnBuild_becomevalid(inst, prod)
	if prod.components.burnable or prod.components.container or prod.components.crop or prod.components.dryer or prod.components.harvestable or prod.components.machine or prod.components.wardrobe or prod.components.sleepingbag or prod.components.writeable or prod.components.deployable or prod.components.attunable then
		prod:AddTag("thisisvalid")

(I know the if is quite long, sorry about that.)

However, when the server is closed, the tag seems to be lost as nothing else that would have to do with it does what it's supossed to.

local old_ACTION_HAMMER = GLOBAL.ACTIONS.HAMMER.fn
GLOBAL.ACTIONS.HAMMER.fn = function(act)
	if act.target:HasTag("thisisvalid") then
		if HAMMERINGANNOUNCER == true then
			if LANGUAGE == "simplified_chinese" then
				GLOBAL.TheNet:Announce(act.doer:GetDisplayName()..has_been_hammered_by..act.target:GetDisplayName()..exclamation)
				print(act.doer:GetDisplayName()..has_been_hammered_by..act.target:GetDisplayName()..exclamation)
			end

(Don't worry about the lack of ends, it's actually finished, I just put the important part.)

If I don't close the server, then the text/announcement that I want to display does appear.

So is there any way I can make the tag not be deleted/stay after closing the world? Thanks.

Maybe use an auxiliary component to save/load the state?

local function oncaninteract(caninteract)
	if caninteract then
		self.inst:AddTag("CanInteract")
	else
		self.inst:RemoveTag("CanInteract")
	end
end

local CanInteract = Class(function(self, inst)
	self.inst = inst
	self.caninteract = false
end,
nil
{
	caninteract = oncaninteract,
})

function CanInteract:OnSave()
	return self.caninteract
end

function CanInteract:OnLoad(data)
	self.caninteract = data
end

return CanInteract
