Double masters coming today.
Site is not dying, you can check the announcements subforum if you'd like to see the regularity of updates.
The imports are not automatable, even though they are and always were done via scripts they need to be tested on local first, adjusted in case of errors, etc. Even so, there are frequently mistakes, see for example the promos I just added last week, one of them is already listed under a separate edition. These mistakes in turn then need to be corrected, paying attention to which printing is adjusted, moved, changed or removed, preferably not messing up the inventory counts for people that already added it to their sets or trades.
If things are too slow or of too low a quality for your expectations, a quick email to support@deckbox.org or ticket, and I refund the premium, no questions asked, I never refused anyone a refund.
