Whenever I try to enable any sky, ground, daycycle, sunflare, etc. add-on, it will not show up in the Custom gamemode list and are not enabled. They do not appear at ALL in the console or ADD_ON_LIST.cs. However, if I manually write in $AddOn__Ground_Demian = 1; the add-on loads just fine but still does not appear in the list. I've caught word that one of the environmental saving add-ons (one adds favorites, one saves with the build) causes this, but after deleting both and ADD_ON_LIST.cs, they do not re-appear.
