Blizzard has been hot on the trail to work on a fix for the bug that caused server crashes in the PTR. Yesterday, the Boost NPC for the PTR server was disabled due to the Paragon boost feature causing server crashes.
This issue has been very unfortunate for players, as without being able to use the Boost NPC, testing out the new updates to Classes and Uniques is only possible through normal leveling and gear acquisition.
