The AI hasn't changed in over a week. Sorry to hear you're running into a bad streak of games though.
If you replace the routine with something else that is modified and are running into troubles, consider downloading a clean copy of the bot and not replacing the current routine version. When NullRoutine becomes the active routine, it's because the other routine has an error so the bot can't use it. Simply change it back to the desired routine if there's an error the next time you load the bot.
