I will take a look ASAP.
Ok, used v4 for install too. Seems like hell broke loose without purpose(and with all necessary wipes).
I'll just try clean install tomorrow, without SuperSU install this time.
Very Strange Indeed...
Are you using a SGP611 or SGP621?
I did a normal upgrade from V3 through flashing boot, system -> reboot recovery -> gapps, Magisk V8, PHH Superuser.
I am using a SGP621 and sadly cannot test the SGP611 builds, because I do not have the device, but they should be okay.
