I think I may have found the issue. If anyone else can confirm this...
My coordinates changed after doing this: I wanted to change the default world spawn. I used the command : /serverconfig defaultSpawn [x y? z] and that did not work. next I used /serverconfig setspawnhere after using this, we test killed someone and they spawned about 50 or so blocks away. I continued to use this trying to move around so as to get the spawn point where I wanted it to be. I believe what I am seeing is that the command did not move the spawn location to where I was standing but moved the entire map coordinates so that where I was standing was centered over the original spawn location. Anyone else verify this ?
