When trying to accept the quest 'Eliminate Goblins', an error message pops up saying: 'The quest has ended due to an unknown error.' This message also popped up somewhere in the Dyle questline, I think it was Nella, but after talking to Shumi, that was fixed. Something else I noticed about that quest is that it is listed under 'empty' which might have something to do with the error message.
This quest line is very broken, it's going to be fully fixed during the next wz update, it has also been reported in the Quest thread.
I see shumi's quest in that list, but not Eliminate Goblins, you can also mark my other bug report as duplicate though, I'll make sure to check the quest buglist next time.
