I cannot put my custom level into a GM scene? I had previously heard to just copy the level into an add-on but for some reason it deletes almost all my custom NPC characters when I copy it. Any tips? I was hoping to play today after spending 30 hours creating everything.
Where are you creating your custom level right now? If it is in an add-on the editor, you can check the menubar for "Level > Edit level data..." and set "Is Game Master Level" to True. Then enabling this add-on for your campaign will make the level available. If you made it in GM mode it is already a scene to start with?
I managed to fix that issue, but after my friends try to load in they cannot see the ground or any of the npcs I had placed. If I add new stuff through GM they could see it, but nothing that I had put in through the editor except trees and bushes.
