@OlVl That seems like a lot, considering projects could be stalled waiting for manufacturing because of that. 
Is there an ETA to fix it? 
@Olv Sad to hear so, it seems to me like a very serious issue if you cannot download your own design for manufacturing. Why would you want to use Upverter then?
