@jor2404 I guess you messed up your pad configuration in ES, first of all. Second, it's been explained in the forum (search user nwildner talking about mapping problems on moonlight)
Thank you for your help!
Fixed with a manual fscheck; system updated to 18.04.20 successfully and seems to be stable.
I'll keep an eye on the sdcard, but for now everything looks fine.
Thread can be closed, have a nice evening everyone!
