A few things of note that may explain some of the entries in the logs.
1. I have a NAS that files were being stored on so that I could work from different locations and different computers around my home. It made file management a breeze since no matter which computer I was working on, I would access the same files. For several versions now, render and save times have been horrendous to the NAS. To improve the wait and frustration, I am saving the "master" files on the NAS, but copying the sequence .xml from the NAS to the machine I am using to do work. I have to remember to copy my file back to the master after each session, but it has made it more tolerable to work with. Hence you will see reference to C:\Christmas\Seq xLights\2019 LWW Main\ and D:\Christmas\Seq xLights\2019 LWW Main. The D: directory is on the NAS.
2. I am trying to update the image files to C:\Christmas\Seq xLights\2019 LWW Main\Media\Images\*.*. I have found no easy way to update image references. I am deleting the image in the sequencer and then reapplying them at the new address. The same holds true for videos, but they are in C:\Christmas\Seq xLights\2019 LWW Main\Media\Video\*.* .
All local machines have the same version of xLights, and a complete compliment of files such as in the media directory, including images, videos, and music.
