When selecting the topic "Background" on Vanis Nithri in Vhul with a disposition of 70 or more, it tries to add the topic "Vanis Nithri", which doesn't exist.

It seems that there is no error message for this during normal gameplay, only in the Warnings.txt can it be seen. I only noticed it because for some reason on my current character the game crashes when I select it, with the error being spammed continuously in the Warnings.txt. That doesn't happen with a new character, though, so who knows what's going on there.
