After yesterday's 2.0.5 update to Diablo 3, the game's developers at Blizzard have implemented a livefix that aims to fix a number of issues that cropped up with the release of the patch.
Notably, some players were using level 1 T6 Nephalem Rifts to farm Blood Shards. To that end, Level 70 heroes will now receive a greatly reduced amount of Blood Shards from playing in sub-Level 70 games so they won't be able to exploit the game any longer.
Here are the fixes Blizzard has listed:
