Now its a minor detail, but it should be simple to fix/improve.
It'd be nice if you could swap what you have equipped with what is on your cursor, especially if it is a lit torch. I know its not much fuel to re-light, but its annoying that what is on my cursor isn't considered in my hand and I can't directly swap it with what the game considers in my hand.
I did search for this so I am sorry if someone else has mentioned it.
I realise it might be a feature not a bug, I'm just say, its frustrating.
