AppCode 2 release code navigation completely confused

I've been using the AppCode 2 EAP for months now with great success, but ever since installing the official release of AppCode 2 the code navigation seems to be completely messed up. Command-clicking on method usages in my code brings me to the correct source file, but completely in the wrong location. This functionality has been rock solid in AppCode for so long that I suspect that this must be a local index curruption or something. I've used "File -> Invalidate Caches..." several times without any improvement from what I can see.

Any ideas on how I might resolve this?
