If you have been playing Tom Clancy's The Division 2, you may have noticed that Ubisoft has been struggling to keep the game online and deliver promised patches. It started yesterday with the scrubbing of a planned maintenance due to unforeseen issues with the patch.
The issues have continued today, with problems with the leaderboards and challenges, players unable to activate Capitol Defender Packs and getting the EU-FA-0 error in the Epic Games launcher while trying to launch the game. A server restart has taken place and the servers are back online, so hopefully this cleared up the issues and the patch is rescheduled as soon as possible.
