Yeah. I can point to an issue though, had a few moments and took at look at the log.

This is complaining about some value being null when it tried to create a zombie cop, in layman's terms. Not sure which mod does what, but I see a bloodmoon speed one. If you set a value that's outside the valid range, you'll get errors like that. You said you removed bloodmoons, maybe some mod referenced it or something. So, that's a general area to look for.
