Did native NVRAM kill my sleep?

My sleep suddenly no longer works, and the only change I have made is removing EmuVariableUEFI.efi and replacing with SSDT-PMC.aml. (I have Gigabyte H370 HD3 + i7-8700 + RX 580).

Has anyone else encountered this behaviour?

PS. I just tested sleep and it worked perfectly... maybe it was a USB device still plugged in or active?
