The game seems to load all files in all folders, which is another reason why making a mod for your edits is preferable. The behavior you noticed, with the game loading a custom-named file is something that can be used to advantage. It would be better to rename the file extension, such that you would have "sensors.sim.bak" or something similar, but I don't trust the game to do that correctly either...
btw, you are welcome, and I thank you for thanking me...
