Are there new versions of Mercury adventures?

I did the daily heroic on Mercury today, and it popped up as Bug In The System but then took me to Future Mercury instead of the past like usual, and had me do the same defend against two waves right below the Saint 14 area. The final boss after the waves were some yellow bar wizards, one of which had a Savathun reference in the name. Anyone else get this version? Seems others had The Up & Up be the daily and I can't find any other references to this. Secrets maybe?
