I noticed a possible bug with the guildleve "Slugging it out", and this may affect all "Temperance" guildleves as well (this is the only one I've done so far, so I do not know whether this affects only this leve, or all of this type).

During the leve, I am tasked with heading towards various areas as part of a patrol, and dealing with the enemies that pop up. However, the area is marked as patrolled several seconds after the enemies spawn (10 seconds or so). The leve mentions that killing the slugs is the purpose of the patrol, so it doesn't make sense that one could spawn them, and then just ignore them for quest completion. Secondly, when the last patrol is finished, some boss mobs spawn (3 crabs for this specific leve). As stated before, this means the slugs can be ignored despite being the purpose of the level (Only the crabs need to actually be killed), but it also makes the leve difficult to solo, as it results in having to deal with the last group AND the boss at the same time.
