It was working great (I love it!) in the mega base and then I went into a different saved map... It worked fine there. Then I went back to the mega base map and the mode would no longer update the text file. I tried toggling the mod on and off and even deleted and re-installed... No Luck.
uhm, right now the write to file is triggered on a change of the amount of trains (aka a train is removed - checked every 2 seconds or a new train is started or stopped) then it will write to the file again, i can make it so it will do this by default when a map is loaded though, noted for next version - working on it
