I'm having issues saving my map

Well… yet another issue…

So, here I am, building my game. I have a tiny bit done, and my friends want to see it… So, I head over to save my map, so I can head to the project settings and tell it to set the default map to my map.

Well, I get a saving error… see below.

The asset ‘/Temp/Untitled_4’ (…/…/…/…/…/…/Users/Michael/Documents/GitHub/Shifted_Dimension/Shifted_Dimension/Content/Maps/NewBloacoast/Main.umap) failed to save.

Cancel: Stop saving all assets and return to the editor.
Retry: Attempt to save the asset again.
Continue: Skip saving this asset only.

Then, I go to save it again in the same spot, and it appears there’s already a map with that name.

I go to the folder in the Content Browser, it’s empty.

It’s also worth mentioning that I get an error saying that it can’t save because it has references to private objects from an external package…
