AutoSaver

Automatically backups your character save and Spike's inventory on game load, quit and every 4 minutes.

Up to 15 saves are stored. You can configure both the number of saves stored and the automatic save interval in BepInEx/config/Marioalexsan.AutoSaver.cfg.

To fix save corruptions:

go to ATLYSS_Data/profileCollections/Marioalexsan_AutoSaver/Characters/{CHARACTER_NAME}, where CHARACTER_NAME is your character's name in ATLYSS
grab the latest backup, or any previous backup based on the time it was created on
copy the file to ATLYSS_Data/profileCollections and replace atl_characterProfile_{X} with that file, where X is the slot you want it to go in, from 0 to 5 (atl_characterProfile_0 is the first slot)
example: ATLYSS_Data/profileCollections/Marioalexsan_AutoSaver/Characters/Chip/_latest -> ATLYSS_Data/profileCollections/atl_characterProfile_0 (overwriting previous corrupt file if needed)

To fix item bank corruption:

go to ATLYSS_Data/profileCollections/Marioalexsan_AutoSaver/ItemBank/
grab the latest backup, or any previous backup based on the time it was created on
copy the files from within to ATLYSS_Data/profileCollections
replace atl_itemBank with itemBank_0, atl_itemBank_01 with itemBank_1, atl_itemBank_02 with itemBank_2, etc.
example:
- ATLYSS_Data/profileCollections/Marioalexsan_AutoSaver/ItemBank/_latest/itemBank_0 -> ATLYSS_Data/profileCollections/atl_itemBank (overwriting previous corrupt file if needed)
- ATLYSS_Data/profileCollections/Marioalexsan_AutoSaver/ItemBank/_latest/itemBank_1 -> ATLYSS_Data/profileCollections/atl_itemBank_01 (overwriting previous corrupt file if needed)
- ATLYSS_Data/profileCollections/Marioalexsan_AutoSaver/ItemBank/_latest/itemBank_2 -> ATLYSS_Data/profileCollections/atl_itemBank_02 (overwriting previous corrupt file if needed)

Notes

This mod assumes your character's names are unique.

If they're not, you might run into trouble as playing on one of the characters will overwrite the autosaves of the other.
