I've turned off the notifications of this mod, and I'm still getting notifications of filled and unfilled roles. Every minute. It's super annoying. Is the option to turn these notifications off not in Register?

Okay, it's every 30 seconds, not every minute.

Just to confirm we are talking about the same settings, on City Hall or an in-game computer,

NRaas > Register > Show Notices > False
NRaas > Register > Show Immigration Failure Notice > False (this one won't show if you have Register > Allow Immigration set to True)
NRaas > Register > Show Debugging > False

I can't believe I missed something so simple, just one option up from the other option. Thank you!

Phew, was getting worried there. Glad that's all it was.

Thanks again!
