Looks like it's back to updating this every time it changes. It takes a few seconds to enable the first time you click it. It may not be totally immune to updates, so let me know if it stops working. This was working for me as of October 16, 2017. I updated the script to try to update itself when they update the game. I may work on more options, but this should help for those that want to cheat some things. You toggle the script and then you can press Shift+F1 in-game to access the debug menu where you can modify many things. I have an option to enable the debug menu in Endless Space 2.
