技能点事件地图无法返回

我完成了全部3章残酷剧情，错过了普通难度第三章过去模式下心脏事件的技能点。当我想去完成时，发现我无法正常回到该事件的地图。
我尝试了很久，找到了回去的方法。首先需要正常传送到普通第三章高地神塔营地，然后进入回到过去的传送门，这时候会被传送到残酷第一章开始。接着原地打开回城传送门，会被传送到没有传送点的高地神塔营地。在往下走，进入淹没之城，在淹没之城传送点再次传送到普通第三章高地神塔营地（这时候才会被传送到正确的400年前高地神塔营地）。才能进入阿戈拉完成心脏事件拿到2点技能点数。

I have completed all three chapters of the brutal plot and missed the skill point for the heart event in the past mode of the third chapter of the normal difficulty. When I tried to complete it, I found that I couldn't return to the map of the event normally.
I tried for a long time and found a way back. Firstly, it is necessary to teleport normally to the High Ground Tower Camp in Chapter 3, and then enter the portal that returns to the past. At this point, it will be teleported to the beginning of the Cruel Chapter 1. Then open the teleportation gate back to the city and you will be transported to the High Ground Divine Tower Camp without a teleportation point. Continuing down, enter the submerged city and teleport again at the submerged city teleportation point to the regular Chapter 3 Highland Tower Campsite (only then will you be teleported to the correct Highland Tower Campsite 400 years ago). To enter Agora and complete a heart event, earn 2 skill points.
