Weird string appearing

[Lochlenn]

Ive now had 2 reports of a mob named #)493414, its also appearing in some text strings as well:
"side that is destined for victory, or I can end your living misery and
ensure that your bones never find rest.' Frozen with fear, I coul#)4934!4%nod my
head numbly. 'Wise choice, mortal,' the dreadful voice growled."

found in gravediggers diary. Does anyone know what this is and how it can be remedied?

Yeah there is a weird bug with the dats sometimes it adds this shit to the text blocks. You can strip out the info with nightmare.

The names tho are another issue. But text blocks just need to be cleaned up.
