Recently, it may be in [e1.5.4], and certainly in [e1.5.5 beta].
Players rarely encounter it, but it greatly affects the experience. It is a very bad Bug.
Two parties are fighting, players choose to join the fight.
At this point, under normal circumstances, other parties within a certain range on the map will join in.
However, in certain cases:
The party at war is just now, Just started fighting.
That there have been no casualties on both sides.
At this time, If players join the battle, other parties in the map will not join in the assistance together.
Once the belligerents get together and the first casualties begin to appear, things will be normal, and other parties around will normally support and join the fight.
