With the latest versions (v0.1.2/v0.1.3), my unit frames will reset their position to the default top-left corner after every load screen (logging out/in, /reload, zoning, etc.).

I have tried disabling all other addons and the issue remains.

This does not occur in earlier versions.

This seemed to be an issue with setting the position by using the default Move Frame -> Unlock Window. Resetting that to default then using the interface controls to position the items worked as expected.
