Game Stuck After Chaos Invasion

The cutscene from the Chaos Invasion starts, the turn goes to me (my friend has just ended his turn) and I can't do anything. Trying to move armies doesn't work, can't build anything, can't end turn, nothing.



A number of people are having this issue now and it's a little bit frustrating having to halt a campaign my friend and I have spent 101 turns on, because of this bug.



Would be nice to have an official response to this, and an ETA as for a fix.



Thanks in advance.
