It's not urgent.
Where can I find the new BTCD MGW?
Is there a way to redo a pending transaction in the new MGW?
Or will that mgw transaction be picked up, when the servers are back up and running?
You can find the new MGW in the SuperNET v2 Beta clients
here. I've added a permanent link to v2 Beta releases in the top of this
SuperNET software releases forum section.
In any case I posted download links in this topic a few posts above.
Whenever you want to report any issue with a transaction, please provide the transaction ID - or at least the Nxt account you were using. Otherwise we cannot track anything down and all we can do is guess. So please provide that.
Your transaction is not forgotten, nor lost forever. No transactions are forgotten in Nxt blockchain. It was simply addressed to a server triplet that, as james pointed out, is now by default offline. MGW has suffered from delays and technical issues, but deposits and withdraws have always reached destination. With the exception of two or three transactions currently related to the (offline) development servers, everything has been delivered. In this case, if development servers cannot be run and caught up with any pending operations in the next days, once we have your transaction information we can solve it manually.
And please be careful with those fast scam accusations.
