Karris' dialogue is weird

Karris Dialogue is rather weird.
Choose "We've discovered the whereabouts of the gnome you've been hunting. In exchange for a little gold on the side, we can tell you where he is. And in exchange for a little more gold, you will find only a body."
Karris will explain that you misunderstood, and that they want him alive. If you want to tell them where he is, the option is "Ahh, well... perhaps he is not worth protecting after all. I lied. I know the whereabouts of Belgin."
But you had not been lying to Karris up to that point, nor did you indicate to Karris that you'd be protecting Belgin in any way.
Anyhow, Karris offers 1500 gold for his location. You can then choose "We could always remove the problem for you, for perhaps 2000 gold? The Guid would charge far more..." when then cycles back to perhaps you misunderstood.
I know lots of dialogue circles around, but in this case, it just doesn't feel right. Is this how the dialogue has always flowed? Because it almost feels like some replies lead to incorrect dialogue states.
Tiax' quest overall felt rather buggy. For example, if you just tell the gnome to bugger off, Karris' dialogue plays out the exact same as when you helped him.

This needs some disentangling together with some tracking variables inside the dialogue to toggle the reply options, maybe also a new line or two.
