It has come to our attention that the January 27 game update for Borderlands: The Pre-Sequel, which releases alongside the Lady Hammerlock Pack, has an unforeseen issue.
Specifically, when the update is applied, putting three items of purple rarity into the Grinder has the potential to cause a crash. The team is hard at work at addressing this issue as quickly as possible -- until then, we recommend players use the Grinder at their own risk.
Should players not wish to receive this update, which is required to play online and access the Lady Hammerlock Pack, PlayStation 3 and Xbox 360 players should not accept the update when prompted to download while Steam players can put Steam into Offline Mode.
We'll share more information on the resolution to this issue as soon as we have it confirmed -- keep an eye on the Knowledge Base article here for the latest.
