Do AssetIDs change?

Hello,
Do assetIDs change while the item is in your inventory? (Without trading it to anyone)

no, assetID is permanent

        parsed_items.forEach(function (item)
        {
            offer.received_items.forEach(function (rec_item)
            {
                if(rec_item.assetid == item.assetid)
                {
                    item.assetid = rec_item.new_assetid;
                }

            });
        });

I use this code to update the AssetIDs when a trade my bot sent gets it status changed to Accepted.
parsed_items contains information about items that the bot used to create the trade.
I believe that sometimes this code doesn't do it's job, because the bot can't find the item in the inventory, am I doing something wrong here?

Assuming we're talking about Valve games and games using Steam Inventory Service (which is not all games on Steam), asset IDs change when:

• The item is traded
• The item is modified (e.g. painted in TF2, renamed in TF2/CSGO)
• The item is attempted to be traded but the trade fails and is rolled back

There are probably also a few other weird cases where an asset ID changes because this is Valve we're talking about.
