I am having the exact same issue, but the mod runs if you remove the New Republic fileset. (And change the number of enabled mods to 5 of course). I guess the problem must be in there somewhere, I have tried redownloading it but it doesn't seem to fix the issue. EDIT: Additional bug, any ship that an AI or player Yuuzhan Vong creates is instantly destroyed. It pops out of the factory and explodes immediately. I could not test the New Republic for obvious reasons but everything was building fne for the other races.
