there is always a "Copy to clipboard" button at the bottom of those messages, which copy all of the content AND also add the appropriate tags for forums to show it as [ code ] [ /code ] blocks.....
So unless you post one of them here, neither veq nor anyone else can help you really.
BUT it's probably like for everyone, always an assign error because it tries to add a new quest to your questlog which it can't find (something seems to be bugging out there... maybe it's just a typo in the assignment or in the quest definition itself
)
