I understand you guys are improving the flow of the game at this moment. It's a complex game, so it needs to be steamlined every once and a while to ensure the good functioning of future upgrades. But what you did last night is a disaster. An unannounced mainenance the night before Fury is really a bad idea. Here is the result on my game.

I play Vikings mostly using Plarium Play on my iMac, alternatively on my iPad-pro. Both devices show the following problem since yesterday's 'upgrade'. Every other minute or so, the the game is slowed down by lag for a minute. This is new, never had it before in five years of play. I tried changing server with my VPN, tried switching it off, checked bandwidth, no effect. My network monitor does not show anything unusual. I posted a five minute video on youtube so you can see what has been going on for three hours now : the youtube code is

I think you will agree that playing Vikings is not possible under these circumstances. I will wait till you get it fixed. I really think you guys ruined Fury. It's plain dumb to have an unscheduled mainenance the day before Fury. Unless this was a cyber attack, in which case you are excused.
