The original issue on this (313723) was put in the Working as Intended area. This is incorrect. The quest was not working as intended and was unable to be tracked. It was not a levequest but rather a side quest. Please review again:

I accepted the quest, Whack-a-Mole from Arenlona at Red Rooster Stead in Cedarwood, Lower La Noscea. I then proceeded to trigger and defeat 2 out of the 3 moles. I forgot about the third and went back to get more quests. After a short while (10 min maybe?) I wanted to finish the quest, but when I tried to view it in the "Map" section it said:

"Unable to open the map at this time."

In addition, the red circle stopped showing. I was able to walk to the location but it no longer registers on the map. I then abandoned the quest and I'm unable to reproduce, however I have a screenshot posted here. I have seen this before when trying to say, click a leve unlock quest. However, this is just a low level generic side quest. All I can think of is that it glitches out somehow.
