Quest Secreat Revealed - Teleportation Bug

Bug Name:

Quest Secreat Revealed - Teleportation Bug​

Bug Description:

So I'm trying to finish this quest that asks me to talk to Edena Guardian and to do so I have to use a stone on the underground of Valencia Castle but everytime I try it, it bug. Actually it teleports me but instead of being teleported to inside of the mountain I get glitched under the map and die, like I was falling.
Tried relogging, tried twice, so I had to go back to the Castle by walking and got the same bug.​

How to reproduce/proof:

​

 

Try change channel to another and repeat. Also on siege channel we have all territories autopullup so its bad to use for quests.
