Questions about the gameplay of Heroes 6.

My friend and I noticed while playing on the same computer that we don't always receive Blood Points (BP) or Tears Points (TP). To get BP, you need to kill fleeing monsters and do evil deeds; to get TP, you need to spare the lives of cowards and do good deeds. BUT! It doesn't always work; sometimes, we don't get a single point for the entire map, let alone fill the scale completely. In the campaign, everything works normally. What's the problem?:smile45:
