I'll start up a clean game ( unmodded except for Nomads ) and see if I can replicate it, shouldn't be too hard.
As an aside I've been running Blackrock, Bushi, Junk Pirates, Kadur, Neutrino, Omni, Shadowyards,Gedune, Nomads and of course LazyLib. Apart from the occasional frame drops after saves it all runs smoothly but I suppose that could be the root of the problem.
Edit: I think this was entirely my own fault. I recently did a fresh download of all the mods I listed and I think I grabbed the wrong Nomad version. I can't replicate on the most recent version.
