That's not it. It's the addition of the new TOD slice. I've already confirmed that earlier in the thread and am working on fixing it. In the meantime, just delete default_global.xtbl and default_district.xtbl that came with the mod and all the spawns will be correct again.
Also, daven, the problem was that you forgot the negative denotation when posting your coords. They are actually
x: -274.654
y: -756.561
z: 907.506
thanks I'll try that when I get home!
