Good evening, and thank you for the program that this site has provided. I receive this following string of text when using the program for the first time in years:
System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
at PKHeX.Core.Extensions.GetExtraSlots9a(SAV9ZA sav)
at PKHeX.Core.Extensions.GetExtraSlots(SaveFile sav, Boolean all)
I may have not read a guide thoroughly enough, and curious what I have done wrong.
