Recently I have on couple occasions noticed that a villages loyalty drop by 2 points or more less, then what it should have
this only happened in one of my village while my other 2 villages dropped loyalty like they should have, and I had a large celebration going on all 3 villages
maybe I´m missing something but seems like a bug, with is making already difficult concurring way too hard
Loyalty loss is first of all random value between 20 and 25 (or 20 and 30 with Romans)
Large Celebration will add 5 points or subtract 5 points if the defender is using one
Attempting to chief from a smaller player (in terms of total account population) will result in a penalty similarly to the morale penalty when attacking a smaller player that reduces the effectiveness of your chiefs as well. The larger the difference, the bigger the penalty
Lastly if you happen to be a teuton, the public festival from your brewery also cuts your chiefs power in half.
