Everyone,
Unfortunately, we have encountered an unexpected issue with the Online servers this morning, causing problems with server connection and, as a result, loss of multiplayer games.
Games that started before 11:17AM CET have been affected by this error and unfortunately, we are unable to bring them back. We are very sorry for this inconvenience.
We just introduced a fix so this problem won’t happen again in the future.
We ask for your understanding regarding this very unfortunate incident.
