I don't know how to manipulate the nexus when publishing (isn't it determined by the compile engine ?). Increasing the max_entities did the trick, as I expected it would. I was just flaming about the lack of proper error code documentation, it was 6PM and I was looking at a couple hours of traffic, I just wanted to go home and forget 3DGS for a while so I got a little hot-headed about it, sorry you all.
