I have been using ShowEQ for about a week now and have noticed a rather odd bug.
I will describe it and if there is any other information you want I will try and reproduce it to provide all I can.
What seems to happen is a mob will spawn on a trigger, such as the avenger's in Eastern Wastes. When they despawn without being killed ShowEQ with an error message similar to the following (I will try and get an exact capture tonight);
MobXXX removed prior to processing.
I will respond with more detail tonight, just wanted to give you a heads up that maybe this will trigger something for someone.
