Quoted from Yelobird:Sad to admit I had the Exact same experience. Scary as hell. The Escalara was for sale the following week. Really wanted it to work but we were instantly afraid of it,from then on.
I also committed this error and rode my Walking Dead pin and Escalera back down my stairs in a hurry. I ended up having to do some dry wall work afterwards, but the only damage besides that was to my pride. I had a bad hip at the time and shouldn't have tried to move the game by myself in the first place. I also got to the last stair and let the game down too low to where it lost the bite on the carpet. I learned two valuable lessons at once. Anyway, I didn't hold it against the Escalera though and continue to use it, but with assistance.
