The plague event calls upon a picture that does not exist, giving an error message, the event plays just fine after that, without the picture, but it's probably still worth fixing.
A few of the new events, revolt, revolution, plague doesn't list what the alternatives actually do, it's just a dot.
I'm not sure if these events are actually yours or if they're part of the base-game, but I think I saw them a day before G released the new patch (and this thing auto-updates) so I'm going to take a wild guess and say they're yours.
