No, I'm having this problem too... Persist partition gets wiped, and /data gets corrupted/inaccessible... Happens with daily using, when using whatsapp, gallery, instagram, etc...Yes, but you wiped persist partition using an unofficial twrp in the first place.
Made a clean flash with mi flash, but did not solved my issues, I'm starting to think my hardware is defective.
Format my phone once a week is not an option, so I'll be replacing it...
