the sentOfferChanged function does not always work

[Risse]

Hi guys! Maybe you know, but why the function

manager.on('sentOfferChanged', function(offer, old State) {
        console.log(`Offer #${offer.id} changed: ${TradeOfferManager.ETradeOfferState[oldState]} -> ${TradeOfferManager.ETradeOfferState[offer.state]}`);
 })
)

it does not work for all trades, I mean that sometimes I can accept / reject a trade sent by a bot, but the function ignores my interactions with the trade offer.
