Hello @Fable... here are the latest news:
The two silly dwarves "are" a lovetalk, no less

(I finally met them).
So "standard" tricks to skip/kill them don't work...
But you can try CLUAConsoleSetGlobal("LoveTalk","LOCALS",31) with mouse pointer on Tashia to progress to the next lovetalk.
They caused no problem to my game, but jumping to next lovetalk should cause no problem as well...
(I tried it on my pc, dwarves shouldn't appear and she should start a lovetalk about war).
You may also want to set Tashiaplot,GLOBAL to 10 (it should happen automatically, but just to be safe...)
