Whilst playing I picked up a Blue wool coat (take to hand) when trying to discard this, I was not able to.

Firstly I tried to discard by placing it into the vicinity section but this did not work.

I attempted to remove the coat by moving an item in inventory into hand slot but this did not work. It may be worth noting that when jumping the Blue wool coat would leave the character but then rubber band back when the character stopped the jumping animation.
