Sorry to bother you all again but I have fully changed over from 5.2 to 5.4 now with my new game and all is working great. However when I undo a command to try something else it comes up with an error saying (Error running script: Object reference not set to an instance of an object.) Can someone help please. Thanking you Terry. Happy Adventuring
