As of approximately December 23rd, 2016, token transfers to the new Nost-Elysium servers have stopped working.
Google reveals users on many other channels (such as the Nostalrius subreddit) reporting the same problem. Elysium has tweeted that this matter is in Nostalrius's hands, and they have no control over it.
The Nost team may be on holiday or may have ended transition support on Dec. 17th, the day of the transfer, but an update (on any channel - Facebook, Twitter, Reddit, etc.) would be fantastic.
Happy new year, all!
