Botanical Research

re: Botanical Research This Quest appears to be broken for me
Following the Green Quest Arrow takes me to the mist gate into Garden of Seborhin from Forum Highlands, entering the Mist gate takes me to Nightfallen Garden and the Green Quest Arrow points back to the Mist Gate to Forum Highlands, the Green Quest Arrow then points me back into Garden of Seborhin but again that gate takes me to Nightfallen Garden .......... ~Rud

I have the exact same problem too....~Mithra

Same here, but I wonder if the quest gets broken if you accept one of the missions that turns the Garden into Nightfallen Garden. ~AC

I followed the story line, and this quest was not offered until after the garden had changed, there appears to be a large number of quests that trigger behind you (in towns you have already cleaned out loooong ago,) on varyous independent triggers as you progress thru the story line, there appears to be no purpose for doing this other than to make the game chaotic and unplayable. ~Rud

I followed the arrow, and I can't get through the gate at all. I'm not as far along with the missions as you 2 are obviously. The quest also doesn't get advanced when you try to take the Tihark Orchard mission. ~Why?

Remember, you need to have Tahlkora along to get through the gate just outside of Tihark Orchard - she's royal blood.

I Found a "Work arround" on this Quest
Take Tahlkora and a single player that has not done the Tihark Orchard Mission. Exit to the East in Tihark Orchard with a full party and talk to the gate guard. Tahlkora is the "KEY" to enter the closed gates. The player who allowed you to enter can now map out. From there you can do the Quest and Explore the area. ~Rud
