Larian Studios Forums Divinity 2 - Ego Draconis (English) Technical problems Reaping the seeds problem...ll

Hi to all! I've got a problem during the quest "reaping the seeds". I made out all the wyverns to get the seed from Jierevas but nothing happen. The tree doesn't give me it. Is it a bug that I can resolve but mself or there is a patch to get rid of it? I don't know if the problem is already came out to someone during the game. Please help me. I didn't save before accepting the quest and now I don't know how to do. Thanks in advance.

Shoot down 3 wyverns.

I did it. But the tree doesn't give me the seed. There are no more wyvern around in all the Orobas Fiords. I think it's a bug...
