Stuck on diplomacy screen [windowed][savegame attached]

[TorbenB]

During the AI turn, one of the leaders approached me to complain about me attacking a station, which is kinda weird, as it is several turn ago that I did and then only because I couldn't prevent an allied faction to attack.

Anyway, I press a button to reply but nothing happens. I press the other button. Still nothing. I'm stuck at that screen. Reloading the game changes nothing.

I have attached the savefile that is saved right before it happens.

Thanks for the save, we're taking a look.

Torben, it appears another player won the game behind the open diplo screen, causing it to be unresponsive. Thanks for the save!
