I feel I have to respond to this part of the official News post:
"Matchmaking
We understand folks are also experiencing issues with matchmaking, which is a critical feature for organized play. To improve matchmaking we restarted Europe Central servers on 2/20 at 11pm UTC (2/21 12am CET) with an expected downtime of 2 hours. This helped stabilize the feature while we work with Smilegate RPG on a more long-term fix."
I play every day in EU Central, and I can 100% assure you that matchmaking is broken solely during the hours with longest queues. It is not a bug, not a corrupted server session. Simply too many players to handle.
So please stop restarting the servers needlessly. 3 hours of downtime you cause by that is absolutely needless and very annoying.
