When it is your turn and you try to get out of the properties list you are no longer able to play.
The only work around that I have found is to save the game then restore the game. This does not always result in a fix however. This seems to be a long-standing bug as I've noticed this in prior versions.

2. Aminiel,
Bug found. It happens when you press V or Shift+V if you are asked "do you want to buy X ?" at the same time.
It will be fixed at next release, thank you very much for signaling.
