The Varjim Quest in the ruined village (area with all the treants and bogs-related monsters) nearby the Western Coasts will not let you close it after completing it.
Please inform if this quest is still broken after v964.
It stated that the quest had already been closed after we went through it today and tried to close it out, about an hour prior to this post. Server was 964 or 965 at the time.
This quest does not report players added to the quest to the person who starts it from the quest-giver conversation. No EFUQS message is given at all, until attempts are made to close it. When the dialogue option "We are done." is clicked, EFUQS reports "A party member has already closed this quest. Skipping end reward." Tested three times, making sure nobody in party had closed the quest. The result was the same all three times.
The quest wasn't set to block. Try now.
