There are currently some bugs in the Dark Temple Time Wandering raid. For example, you cannot queue up Time Wandering BT after playing normal BT. Also, the way the egg knife transforms is wrong!
I made a mistake. The problem is not with ordinary BT, but with the different progress of the time book.
For example, if you quit midway and have the progress of Time BT Lao 2, the opposition team will not be able to join the queue, and then the team leader will check your progress and ask you to get out.
There are a large number of groups in the pre-group that only require new progress.
Therefore, try to find a reliable group to get through it all at once, otherwise you will have a lot of trouble due to progress issues.
