Quite a few times over the last week, connection with the game has broken, and then on re-logging, the process will throw an "unspecified patch error" message at the game data check. After waiting an hour or two, logging proceeds without issue.
For what it's worth, connection is good, trace to server-side is good, client-side game data is not corrupt, no issues with hardware or the operating system. I'm assuming it's a "Turbine issue", but want to make sure. Thanks.
