Side quest

I have a side quest where the text does not match the requirement. I was told when asking in chat that this quest was changed. It seems very strange to me to change what is required in a quest, and not changing the text telling what is required.

I am asked for an epic building, a castle or something. I do have a Dark Castle, but that does not solve the quest.

I was told that only thing that does solve it is an angel gate, - that is not a castle, I think we can agree on that.

I guess I can as well delete the quest or use gems to solve it then, or use the 150-200K to get a gate in TO, the chances of finding angel gate is 2% in SE.

A dark castle used to complete that quest, about the time you joined the game it changed for a reason which has never been explained. Now only the Angel Gate fulfills the quest.

you can just borrow a gate from a guildy or friend that has one, only takes a minute to do

I dont know anyone who has one. No one in my guild has one.

It is very stupid with a quest that ask for something, and it is not what is needed to solve the quest. So the text or the requirement should be changed so that they match.
