Hi,

I don't know if this is a bug or if it's meant to be like this, but
npc.alignment seems to be read only. Core-changes.txt should
better mention that, if it's intended. Otherwise, it would be very
useful for us if you could make it writable.

Thanks,

Due to the way alignment works with the npc setup, it's read only.

However, with the reputation system hook, you can technically override the 'alignment' with a highlight color hook. Thats what the client determines to use for the criminal warning prompt.
