What was the problem with the Civic?

I have studied the video (as you can imagine) and would say that initially it was running OK, and then it came off quite hard against a barrier, thereafter the guide definitely hit a particular track joint on the subsequent runs until Ade gave it some attention. So it looks like maybe the guide was sticking or dislodged or even perhaps the guide holder in the chassis has cracked ? Hopefully will be OK on the wood tracks (fingers crossed)
