A Bibarel has ended my Nuzlocke (Probably)

Refreshing the map was a feature removed in 1.2.0 and beyond, though the keybind is still in the options. If you haven’t saved 3 times already, you can revert to a backup save.

A guide to do so is here:

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.
