Loading assets as templates doesn't seem to work on an macbook air (with El Capitan 10.11.6, using Kenney Studio NXT 0.1.2). I saved the asset as a template and I find it in my Finder (looking into it with a text editor shows that at least something was saved). But every time I load it, it just opens an empty template.
Furthermore, I don't know if this issue was raised before, it would be great to be able to return to the "Studio Main Page" after creating an asset.
