Hey Mexto!
Saves are located in ahitr_storage (example Internal Storage/documents/ahitr_storage). They will look something like "1-1-lt1"
If you still have saves like that, back them up/upload them somewhere.
To avoid conflicting issues, delete all your AHITR folders/files and follow this fresh installation guide here: https://rift.ink/3PADL3p
After, you can place your saves in ahitr_storage and resume where you left off!
