I recently returned form a trip to the world. On July 12th while at MK after Wishes I got in line for BTMR with a fastpass. I was already to be in the next train to come in. After a minute with no train an announcement was made that the ride was temporarily closed. Soon there were more CM's and suits arriving to help evacuate the trains. I would like to know if anyone knows what the problem was that night. And also to any CM's out there, When the problem occurred they opened a cabinet full of blue locks and distributed them to all the cast. They also seemed to be writing something on the back of the cabinet. I am just very curious what these locks were, and why each CM was getting one before going out to the trains.
