Over the past two days, usually between 11PM PDT and 12AM PDT, players have been experiencing crashes and disconnects due to a server-side issue.
We are currently working to fix this, and have already implemented some server-side changes which may have resolved the issue. Depending on the efficacy of these changes, there remains a possibility that these issues may occur again tonight between the stated timeframe.
This post will be updated with further information as needed.
