The starting point of the carrat race appears to have any characters nearby to say the lines of saying go on repeat over and over again in seconds. The amount of times they repeat appears to be random, however it can reach numbers of repeats that would cause the player to be unable to move until the repeated lines are over.
Steps to Reproduce
building the carrat race starting point and idle near by the bell for a short while.
