Found a glitch in Profound Red

I was one of the lucky winners of the new Carol Reed game "Profound Red" and have been enjoying playing. Today, I found a glitch in the game.
Not to give too much away , but at one point you open a box to find a key that fits an orange cash box. When I used the key on the cash box, I heard the audio sound of a lock opening, but the box does not open, and continues to show the 'gear' icon indicating there is some action to be performed. I can't simply retry, since the key is now gone from inventory. I will try to go back from a saved game and replay up to that point to see if it happens again.
Has anyone else had this problem? Do you know how I can report it to the developers?

Thanks!

We discussed it here.
