The system was updated this past Thursday via Software Updater when told a new release was available. There were no glitches and the system booted into 18.04.1 normally. I've been seeing quite a few notations in my syslog that I fail to understand so I'll be asking quite a few questions. The entire notation from the above subject is:

Aug 18 18:09:43 localhost gnome-shell[2503]: Object Meta.Background (0x561c9cb0e990), has been already deallocated - impossible to access to it. This might be caused by the fact that the object has been destroyed from C code using something such as destroy(), dispose(), or remove() vfuncs
