I'm encountering an issue where my game crashes when trying to access the Treasures bag while in the Underground. When loading the save file into PKHeX and navigating to the Underground button, I get the error message below. Any help in understanding or resolving this would be appreciated.
Exception Details:
System.IndexOutOfRangeException: Index was outside the bounds of the array.
