Pretty sure it is off player location since chunks are loaded and unloaded off of player location and that would determine the outer limits of where they could spawn. Someone more familiar with the code would have to tell you whether the spawn distance can be adjusted or not.Yeah since 17, I tried shrinking my base fence size but they still spawn inside the fence(some not all), makes all my blade traps a bit useless. Do they spawn off player location or claim block?
