Well, hey!
I myself have been active/involved in software engineering, and as such, I've had to delve into the depths of stuff that can throw things off, I can relate!
As such, I do want to give credit to the Asobe/Lightroom "team", because I/we have seen them work over bugs over and over again. Just realize, I'm not talking about all the Photoshop do-hickeys, I'm referring specifically to the Lightroom team. from the beginning, I've seen them step up and address "bugs.
I'm just saying this because I've seen good results from folks coming out with bug reports, and I've seen the team working to resolve these bugs, I think that they really do work hard, and have earned some respect in that regard!
So, as far as the current issue, I'd say try to be patient, you really do have a dedicated team working on things, so I'm just saying this for a bit of a historical context!
