A friend made me use GIT for the first time. I must say that versioning tools like that can be great. A bit of an effort to set them up, and if you forget to regularly check in your changes, you are as shot as you are if you don't save. But if you manage to make that your second nature, you get nice stuff like coloured comparisons of file versions. That would have drawn your attention to the deleted name, or any entered 7.
It should also be fine for route building. You feed it with Tracks.bin and the Track Tiles folder all the time and it stores all these versions. Until now, I rename them to keep multiple copies which is important as you never know how long it will take until you find your mistake, so the good copy could get overwritten.
