This would probably be a pain in the butt to fix, but...

A lot of non-law-enforcement related greetings are sneaking their way into Greeting 0. This means that the vanilla Oath of Silence at the top of Greeting 1 is sometimes not being triggered correctly (aka, when just about anyone talks to you: exceptions being some forcegreetings and some quests that use Greetings to continue an encounter).

Only ones in Mainland that don't belong there are TR_m1_noga-togroi, and as a creature that can only speak its own lines it doesn't matter (but they should be in 5)
