There is a quest that I am stuck in and cannot complete. Because of this I can't start new quests. The broken quest in question is the one that is given by the guy at the docks of Ocllo. The problem happens during a subquest of this larger quest. The subquest is given by the tinkerer's guild in Trinsic. The quest is to paint four monsters. But he only lists three of the four (the fourth space is blank). And so it is impossible to know what the fourth monster is and therefore impossible to complete the quest. I even ran around attempting to paint every monster I could think of but with no positive result.
Please help.
