After scheduled server restarts the domes revert back to default color and shade. How do i save the desired settings?

You still have this issue? 

I found a fix, i renamned the plugin ZoneManagerDomes.cs

As well as inside the plugin and also changed the class from ZoneDomes to ZoneManagerDomes

Oxide and carbon load plugins by alphabetical order, and Zone Manager needs to load before Zone Domes to create the zones BEFORE loading the data from zone domes.

Hope this helps
