Have been playing since the beginning of this game. Have been a farmer this entire time. Recently I began to notice that when I run up to a mats site and attempt to click on it another player, 1 to 2 meters away, runs up and takes the site away from me. I am not making any errors here and am deeply experienced in farming. The reason I think there is an add on that uses the usual local monster ability to interrupt my attempt to collect a mat is the after effect. That of not being able to click on to another mat without at least two attempts, just as you would find from having a local monster get a piece of you before you arrived at a mat collection spot. There are specific players who use this add on and the results are consistent while other players arriving from the same distance do not use this. I have confronted a couple of players, they both claimed no knowledge and then both said they were sorry, were distracted and would be very careful next time. Both run away when they see me now. Just turn and disappear. Should I begin to list the names of those players I am resonably certain have access to this tool? I don't particularly want to but I would appreciate some sort of response.
