Has this problem been fixed in BIAB 2014?

I have my song setup in BIAB 2013 and click GenPlay every time. But this changes the mix within the RealTracks so I get different patterns of playback. Right now I'm working on a song and have exported the audio tracks into my DAW. Now I want to go back into BIAB 2013 and make some changes to one instrument but when I click GenPlay I'm getting a completely different cello melody on my intro. I keep clicking GenPlay hoping that BIAB will toggle through to the right mix but it's very random whether I get back to it. I know about Freezing tracks but have found the mix can still change even when tracks are frozen.

Hope I've explained it properly? So my question is, has BIAB 2014 fixed this yet or is there a solution?

Thanks
Paul
