Better Imperial City.esp is at the bottom of your load list. BOSS wouldn't place it there. That for one should not be the case, along with the rest of the stuff that is below you're bashed patch.
Also, you've got a mod that is upset over one of its master's in their; not a great recipe for stability.
Yeah, I fixed the out of order master. I did put Better Imperial City at the bottom because I was having trouble with overwritten meshes when I left it where BOSS put it. I'll have to do some experimenting and see if I can figure out exactly *which* mod is causing the overwritten meshes and see about moving that one, rather than moving Better Imperial City. Also, turns out I was using an out-of-date version of WyreBash. I upgraded and hopefully that will help me sort out the problems better.
