Mac Mini going into Safe Sleep after 10.13.4

[I Need a Drink]

After installing 10.13.4 on my Mac Mini, it seems that it is going into safe sleep after 4 hours now. This is a 2014 Mini that has worked fine from Yosemite though High Sierra 10.13.3 as far as not going into safe sleep. I have it set to Power Nap so that it will back up to Time Machine and can receive new emails and iMessages, but it doesn't appear to be working anymore. I used to be able to wake it up by just tapping a key on the keyboard. I use a Logitech K750 with a USB dongle as I don't particularly like the Apple BT keyboard, but now I have to press the power button when I want to wake it up which is not a big deal except for not having current backups or all of my messages readily avaliable. My iMac works just fine, using the same type of keyboard on 10.13.4, but the Mini just won't wake properly. I have tried a SMC reset and that didn't do anything. Is there a way to turn off Safe Sleep or is this a bug in 10.13.4?
