Group ride diverted to two routes

This morning on the TTR Monday Recovery Ride we were scheduled for Wandering Flats. Forty of the Sixty riders made a left out of the start pen and followed Flatland Loop. Sweep also directed to Flatland. Needed to turn off fence to keep riders on wrong route from being removed even though they not show as flyers. They got countdown timer. I did see two others riders coming up Castle KOM as we passed could have been three routes? Has this happened to other rides recently?

One rider also got a message that his free trial was almost over. He was riding with paid account.

See this thread:

Yumezi routes are having issues except Flatland Loop.

Happened to Ascenders Social Thursday in Yumezi too.
