Flatlander and Ched80, thanks, I appreciate the quick response.
@Flatlander - I removed the dispcaticons as you suggested, but that did not resolve my issue. I am posting my rpg_setup.fpi file here.
As an example, I have a dynamic entity 'bread' which I am able to pick up. However, when I press the 'i' key to display inventory, nothing happens.
