6. If the scorer’s table or the referees make an error in scoring, timing, or a call, the referees, the scorer’s table, and the league shall immediately stop the game, discuss the available information to correct it, and handle it according to the following procedure:
   • If the error is discovered during the game, the scorer’s table must sound the signal at the next dead ball to notify the referees to stop the game, and then correct the error.

7. Rescheduling requests: teams must submit a request at least 14 days before the original game date. Late requests will not be accepted and will be treated as a forfeit.
   Application process:
   1. Submit the rescheduling request form and notify the league through the game-operations group or the official LINE account
   2. The league will make the adjustment immediately and notify the requesting team of the result within 7 days.
   📌 Example: if the game date is February 18 (Sunday), the deadline to request a change is 23:59 on February 4 (Sunday).
8. A player may not be registered on two teams in the same group; however, as long as the player meets the age limit of a level, the player is not restricted from taking part in multiple levels. Cross-level restriction: a player may play in any group of the next level up; a player who plays in the top group of the next level up may only play in the top group of their own level.
