About the zombies, it's probably NtotSC affecting the dialog and quest journal entry. 

About the bounty hunters, they are now a random ambush, meaning they will attack you during travel. between areas.

Yes, most likely NtotSC as when I played without SotsC in past, farmer would say (I think he would opens dialogue mili second after main final dialogue is done) to tell you there is strange activities at north (pointing at NtotSC areas and events).

Now, similar happened but seems in bugged way. Moment all is done, farmer again mili second again starts dialogue, but repeat last said thing, and that is (and that probably keep another Quest entry open and unfinished, it dont seems to be SotsC fault).
