I'll answer 2 questions.
1 - Yes, saddog is German.
2 - I know of errors with pregnancies, clothing, reappearing dead people, etc. It's part of the game. What I assume happened is that when certain parts were added, during the planning or playtesting, it wasn't accounted for or was put off. I mean, if I was a bugtester for this one, I'd notice it and say "hey can you do a few renders for this" or just not run it now that she's different which would mean adding checks to scenes which can be a mess. So either way, it's not fully fleshed out.
I won't fix the errors right now because of 2 things. I don't know a thing about daz. And like The Legacy, I wait until it's done or nearly done then I'll take a look. But honestly, SAZ is several orders of magnitude above my skill set there so I'd wait for the SAZ mods. So I'm deferring to SAZ with this one. Ideally if you have questions and would like something added that SAZ would agree with and/or implement, ask him. But first, please read his thread and pay attention to his comments.
