There were no major problems according to Lee. He said that is was a minor issue that was simply a headache. Don't know where you got your info from, but I'm going with Lee on this one.
Well...yeah...that's kinda right.
According to my information, and all this goes back months, they had a serious engineering problem or two to solve. Giving them some headaches.
But at no time did they get to the point where they came close to pulling the plug on the ride.
So...serious/major problem...but always going to get worked out.
