Um rather than making another thread I thought that posting this here would be better.
I've found that when you go to edit your showcase the "File Encoding", "OTO.ini Aliasing" , and "Voicebank Configured On" under the "Voicebank Info" tab go back to what they originally were when you were making the showcase. So if you edit something you need to go back and select those things again.
I don't know if that's something you can fix or it was on purpose or anything, I just felt like I should mention it.
