Two things I noticed.
1) In the Send Resources menu in a team game on turn 7, all the radio buttons were grayed out which meant I could not send resources to my team mate or to other players. The instructions said I should be able to do so after turn 4. In an attempt to workaround the bug, I hit 'reload' page. Once the page was reloaded when I went back to the Send Resources menu the radio buttons were enabled and I was able to send resources.
2) The Lords of Light and Dark scenario map has restricted production for the Dark and Light sides (as opposed to restricted production based on a city). I noticed that when I capture a Light city as a Dark player and hit 'plunder' I always get 0 gold. So it appears there is no production in the cities. But I know that isn't true as the Light player is simply making units that I am not allowed to make. So there appears to be a plunder bug related to your production limitation rather than what is actually in the city.
