So my gobs in my current little idea is vanishing, I'm using the Zul'gurub map accessing it via .worldport -11916 -1260 92 859 4 and we've spawned a few buildings in, however upon flying around a few hundred years or so within the whole region things starts to vanish, they go invisible and nonexistant and only returns upon a relogg, however if you move again then once more turn invisible, I've added a few images as to try and describe my issue.
