After a tournament concludes each lord and lady that are present should have a chance at gaining a boost in relation based upon your relation with them and their personality type if you win. If your current relation with the noble is too neutral then nothing should happen, but if they are a friend then it should go up and if they are an enemy it should go down. Currently this is working for ladies, but not lords.
It appears the personality type was pulling from the wrong slot for lords from a TPE 1.4 update. This has been corrected for Floris 2.6 and TPE 1.5.3.
