RideWithGPS have implemented a new auto 'spur removal' feature. I've tested it a bit and it appears to just remove short spurs automatically, not longer ones. For those who use this tool for planning square bagging rides, that'll be something to watch out for.
It's a pity there isn't an option to switch the spur removal feature off, but I guess for the vast majority of users those spurs are unintentional.
