I have a button running a script. I got an error during runtime in the client that did not seem relevant to my button’s mouse event script. After reviewing my pythong code, I saw that the indicated object was not even being used. I cleared all scripting out of the button events, totally blank now. Saved and ran the client again getting the same results. Is ignition holding on to an old cache of script? This is an issue since after a number of tries and variations, I can no longer have any type of sscript in this button since the client will always run some old faulty script.
