You are most certainly incorrect here. Providing logs as directed in our wiki absolutely provides journalctl output.
Not necessarily… It could be possible that we see a glaring mis-configuration of your system that would easily explain your symptoms.
There is no relation. You are conflating two different issues and are assuming them to be the same. System crashes are a completely different issue to the skin changes being lost issue. The skin changes lost issue is addressed (previously in this thread as well as numerous other threads on the forum) as being solved and the solution is available for testing until our team is satisfied that it is appropriate and should pushed as an update to all users/platforms. I stand behind my direction provided in my last post.
