Unable to complete the quest

[RyukoPS_steam]

The quest tree isn't accepting requests. The menu item isn't appearing. The client has rebooted(Ender). No results.

I have to resort into wildly guessing, but..

Could you try not being horseback?
Could Ender have a bug specific to this? Can you try a different client?

Have you previously/recently delivered quests successfully, while on horseback, while using Ender client?

pickup the item then click tree?

Based on the fact that he is doing a Strider Credo, I would assume he knows how delivering items to a quest giver works.

Also, try different adder meat?
Just in case it's deepwormed meat or something, quest mechanics are so sensitive

I had this happen when there was another quest giver with the same name, and also when the other quest giver that had a slightly different name that started with the same letters.

When there were two quest givers with identical names, I was able to see the pointer to the second one and go find it. The pointer suddenly jumped and pointed in another direction. (W-15)

The first time the second quest giver had a slightly different name. As soon as I destroyed the first quest giver I got a pointer to the one with the similar name, but was unable to make delivery. Since then I have never had to destroy the qg to get the second pointer.

This is definitely a possibility. I remember some world having two Thingwalls that had the exact same name (they were in different continents, though, I think?) so there might be some missing fundamental check for things like that. Albeit that Thingwalls are only ever created once during the world generation, while quest givers are dynamic.
