I was having a friend start their character before I downloaded the DLC and they were looking around their environment when the carriage looked like it rolled over and made crashing lumber noises, then it was upright, and the dialogue continued as if they crossed the gate but then they glitched upright to where they were before the buggy crash and helgens gate closed, and they couldnt even start a new character, and I was wondering if this has ever happened before?
