I have a small filename bug on export.
If I export with the default name of 'skeleton' I get three files:
skeleton.atlas
skeleton.json
skeleton.png
If I rename skeleton to 'skeleton.foo' I get:
skeleton.foo (.atlas extension is missing)
skeleton.foo.json (correct)
skeleton.png (.foo part of name missing)
Similarly, if I rename to 'skeleton.foo.bar' I get:
skeleton.foo.bar
skeleton.foo.bar.json
skeleton.foo.png
So the .json file is named correctly, while the .atlas file loses it's extension and the .png name seems to be stripped of any extension and then .png added on the end.
Nothing I can't work around but it would be nice if I could do this in to keep my naming conventions consistent with other things.
