Territory war clarification

Dear Warlords, for the Territory war last night, you must have been observed that the unfinished battle was still going on after territory war ends.
And we have known the problem that players were unable to join in battleline at that time. It is a design philosophy that we wish not to end the instance battle all of sudden but still wish to avoid further chaos after the event is finished.
However, we found that some player exploited this mechanism and started the fief attack at the last minute and defending houses were unable to react in time and defend their fiefs, which is not what we wish to see.
Based on this, we will adjust the mechanism in the next territory war. And we would like to clarify the rules here.
- After the end of the territory war, players will not be allowed to open a new battleline. The ongoing battle will not end immediately, and both offensive and defensive sides can continue to enter the fight.
