Blood Thief Exploit Hotfix Explained
Blizzard chooses from multiple steps of action against exploiters of the bug
Blizzard used multiple levels of punishment for the players who exploited the Blood Thief Goblin bug, including rolling back certain accounts to the start of Season 3 or when Patch 2.2 landed. Community Manager Lylirra details the actions taken, and why.
One side effect of the hotfix is that all Treasure Goblins now only drop items for players who were in range when the goblin was killed. This makes split farming a little less rewarding. The portals that occasionally come from killing a goblin, that leads to the Realm of Greed, are still accessible by anyone who was in the game when the goblin was killed.
Some players who were given actions on their account for exploiting the Blood Thief Goblins issue, decided to use the official Account Rollback system to try to get around the punishment. That was dealt with, as well. Reportedly those accounts were once again rolled back to the start of the Season or patch so their hero progress was deleted, and all three of their official rollback allowances were removed. It is really not worth trying to cheat, folks!
Grimiku took to the forums to discuss a year-old thread, where he had originally mentioned an idea that the developers had for changing all materials into currency-style user interface. That system wasn't implemented, but there have been gradual improvements through multiple patches, to make crafting materials and gems easier to pick up and store.
