I have been playing a few games in elemental where there are only four opponents, I'm not sure if this is happening with everyone but Umber seems to be the only faction that doesn't recognise their children have been married off for purposes of increasing relations with them.

In addition to this I have noticed that the movement of units targeted with Haste have the benefits permanently, for instance if I haste a unit over three battles will still go into the fourth several turns later with over 7 movement. Just some information for you guys to update
