Just guessing but maybe you were in an instanced area? When I was getting the fishing achievement I would sometimes group up with guild members. There were times when we would be fishing the same hole but couldn't see each other. The reason then was because one of us had completed quests in the area and the other had not.
Think resources should be one for each instance only but you get bugs, another example is players who is invisible in dungeons.Bonzodog01 wrote: »Someone else got the node in another instance.
