Yeah, I was wondering about these Albino Deers for a while. Thought, there’s was something in the water… Anyway, good news about 2 New Routes at Makuri/Neokyo Map. This Z-World expended significantly lately…Ride On
@Didier_FERRIBY when that happens it is, most likely, an issue with your device dropping the internet connection for a period of time. You might need to check that, or hardwire the device on which you are running Zwift.
