Hi, I´m new in this, I receive this error when I try open Events in Spanish Emerald save.

Additionally, I found a bug. When I waht to change the event for Beldum In Ruby or Sapphire, it has 2 checks in 2 flags: 0298 for Beldum itself, and 0968 for the pokeball in Steven's house. When I try to check or uncheck the last (0968), it automatically change the order, don't save; if it's checked and I remove, the check returns, and the inverse process too

Thanks
