I was getting ready to leave and set my wagon team on a loop to train the horses and had the game sent to the tray. When it is in the tray I can't hear the sounds from the game, but all of a sudden I started hearing the clumping of hoofs, the whine of horses coming to a stop then a loud whistle. I went back over to the computer and brought the game back up on the screen to see the wagon stopped on a bridge and my character which was off the wagon getting back on the wagon by itself then turned the team and finished the to the loop end and stopped. When I checked the map to reset the loop I could see a flashing green dot where the wagon had stopped and my toon got back on, also this toon does not have a horse whistle, so am not sure what that whistle noise was. I reset the loop and it is going like normal so far. What would cause this anomaly?
