How to "accept" receiving new items in TF2?

[Robert Lutece]

Upon accepting a trade offer, my bot's inventory is sorted by class (presumably: tf2.sortBackpack(0)).

However, as you can see in the picture, it is only partially sorted, possibly because I am not "acknowledging" the new items and they do not behave normally.

I can find no other explanation - I have tried everything. Please, help me.

Acknowledging a received item is done by simply moving it to a backpack slot using setPosition or by sorting your backpack again using sortBackpack. sortBackpack only sorts your backpack once; it won't stay sorted when you receive new items.

I use the sortBackpack() method after every time a trade offer is accepted. In fact, since it doesn't seem to work for me, I execute the code several times.

sortBackpack(n = 0) is the closest thing to "sort by class" in the range n = [0, 5], so I feel like I am not acknowledging the new items. What am I missing?
