Nobless quest bugged

hi,

i'm just trying to do my nobless quest : soul testing. on 17th step of this quest, we must plant a green seed of evil fragment. i tried both rune and aden castle, but i'm not able to plant it : nothing happens when i double-click on it. i tried with and without selecting the helping device.

is there something i did wrong or is there a real bug ?

 

the area where u should plant the seed isn't in your spawn point. try to find new field on east (in game) from your spawn.

 

as much as i remember the npc gave me a scroll that i teleported right in front of the spot in rune castle i used it and all fine

 

yeah, that's it. it finally worked, i don't know why it wasn't working before
