First time it’s happened to me, but I had a caravan turn up and when I clicked the icon to show his store, I got an error. This resulted in the store window being empty and most elements on the screen freezing (I could still click through the toolbar in the bottom middle, but that was about it). Using F5 fixed the problem.
This was another situation where I was playing in 2x speed.
