The Force rolled back only once.
The first half of the season, the ride was plagued with anti-rollbacks that wouldn't disengage. As some of you probably know, there are two wheels that drag along the lift sled's track, generating an electric current that pulls the anti-rollbacks off of the track. When the wheels stop turning, they fall into place and prevent the train from going back the other way. For some reason, they were dragging anyway.
The other problem was excessive wheel wear. That appeared to be fixed by replacing some wheels (not in any pattern that I could detect) with concave wheels. I assume they distribute the load more evenly across the surface of the wheel, causing more even wear. Since they're nylon, they also appear to be faster.
By July, they seemed to have these issues worked out.
