Neither of these items was saved. The exact same thing happened with my magic ponds, but it wasn't as critical there. However, I manually added what was needed directly into Raelag (2) by opening it in Notepad, and it worked. And the shared resource probably fixed itself somehow during the process. I transferred this model to my version of the map, and now I'm absolutely sure that I can repeat this... with this model). I am very grateful to you for the training.
But now I'm going to move on to those ponds, and my gut tells me that I'm in for more surprises from the editor – it's no coincidence that I can only copy files, but it doesn't see files nested in a folder. I don't know, maybe I'll have to reinstall the editor, but I don't have a backup copy of it; I didn't think of it.
If anyone knows where to get the original, undamaged editor, please write here – just in case.
