Thankfully the developer reacted quickly.  Difficulty dropped all the way from 67000 to almost 0 then back to 45000!  Over 1000 blocks mined in the last few hours alone at near 0 difficulty.  I thought that it's related to the difficulty collapsing exploit explained by SunnyKing a few days ago.  Having network hash rate going from 100~200 Giga hash/second to 4.5 Tera hash/second, then back down again is just crazy.  This is almost as bad getting 51% attacked by a pool.
