I've posted the issue I've been having with this a couple days ago and haven't heard anything.
However, I think I may have an idea as to what is causing this....problem now is how to back out
I have been testing on 2 dev sites, a live test site and my actual live site.
I noticed that everything was working until I imported the dummy data then all of a sudden, not only did I lose my customizations on my actual live site but I'm now experiencing the same problem when trying the modify the theme style using the Theme Editor. None of the changes are saving to the default style sheet instead they are being updated in ->uploads->dynamic_avia->replete.css which requires that I copy paste the contents of replete.css and paste it into the CSS editor every time I make even the smallest adjustment.
Can you look into the dummy data and see if there's something in the file that is causing this issue to occur (nightmare :( )
Create a new thread and tell me what problems you are encountering and what you want to know. 
There is no step 3 :)
