Weirdest chain failure I've seen, and the only one I've ever had on a 95 robot. Master-link was good, fractures are on opposite sides of the chain loop, tensioners were installed and slack(ish), and our nominal FoS is around 4 or 5. Bizarre...

This was my biggest concern, along with cracking wheels, when designing this year. I would suggest getting a lot of spares for competition. Going over the obstacles and slamming into the ground will definitely break chain, as you saw first hand. At least it happened now and not at a competition.
