कारण: Although the rules allow walking to spawns due to Fraud's AI occasionally bugging (though Fraud isn't in this category so it's mostly for convenience), we do not allow accessing checkpoints and opening doors before starting the run for BTG% runs. All doors must be opened after the timer has started, and the use of checkpoints obtained before the timer was started are not allowed. I am sorry if the rules did not explicitly state this since it was mostly implied but I will be making that clearer in the rules now.
