My game crashed after 37 hours of play time

[Dechozen101]

Saved in the middle of a cutscene now my game is frozen! HELP!

Load a backup save, the default save file of the first save slot is Game.rxdata and backup saves are named something along the lines of Save_0_Backup_1.rxdata. Simply move away your current save file, rename the backup of your choice to Game.rxdata and keep playing. The backups update every time you save.

Try using this guide to load a backup. Before talking to the champion, try turning off Wi-Fi searching.
