As the title suggests, it means that when character is transported by NPC or when character leave a specific instance (Ancient Treasure Hunt), character will be transferred to the wrong place. Until now, 2 patterns confirmed.
1. When warping from Varanas Gate to any location in the castle, such as East, West, Central, character is transferred to the Gate instead of the designated destination. Occurs rarely.
Although, I have witnessed this several times already for several years.
2. After the end of Ancient Treasure Hunt, character is transferred to a completely different location (Residence. About an hour ago, the character was using a transport stone to move from that location to the residence.) instead of the Saccilia steppen.
In this case, the character was transferred from Ancient Treasure Hunt to Silver Spring.
Confirmed only once at this time.
By the way, it's unknown whether it occurs also in other instances.
Ask for a fix. Regards.
[Postscript]
Because it's such a unpredictable stuff when it occur, I guess that probably difficult to provide a reproduction video, this time.
