Rojo has trouble when a file is renamed

[evaera]

Version: 0.4.8 (plugin and server)

When renaming a file, after the next sync (whether it be polling or a click of the Sync In button) Rojo will produce an error and then the newly named objects will appear, but the objects with the old names will persist as well until I click Sync In manually.

Here, I renamed "HelloWorld.lua" to "helloWorld.lua", and then I renamed "Model.json" to "model.json".
