I have encountered a bug sometimes which gives a rider too much energy. It starts when I go to the team order menu late in the stage and see a rider with full yellow energy. When I switch to this rider he will drive really crazy with way too much energy.
You can see the rider staying at full effort/attacking for 25km before the yellow bar going empty. I don't know why it happens but I wanted to report it if it is not already known. You can also see a downhill glitch at 5:15, I open the team order menu in the middle of a turn and instantly snap on to the green line without losing speed. Sorry it is very late I only bought the game a few weeks ago.
