I am currently playing a BGT game with an altered selection from the 'Recommended' mod template from the Big World Setup (have attached the WeiDU.log with the post).
The flaming fist mercenary who was supposed to appear after interacting with Viconia in Perdvale does not appear, upon interacting with Viconia just triggers the following dialogue "I am so sorry to be nervous, but the surface is so large, unending when compared to my homeland".
Is there any method to get around this?
