First of all, let me congratulate everyone who has been working on the quests, they are fantastic. I've almost finish a particular quest, but I found it very hard because the NPC did not accept the right sentence which was something like Thr[...] the Dw[...] [....] where I have removed many letters to avoid spoilers, but it did accept Thr[...] Dw[...] [....] , where you remove the "the".
I spent quite a lot of time on it before I found a post where a similar issue happened which helped me.
Perhaps, you could also make the NPC understand similar answers (which I have tried), such as "in the sky", "above your head..."
(we should perhaps erase this post once it has been treated to avoid spoiler).
The quest I am referring to is D[...] W[....] wants the messenger b[...].
