The chat messages are (mostly) made up on their discord by any member, so dont realy worry about continuity
Viewing post in Stream chat error?
Not caring about continuity in a story-driven game?
Perhaps we should write a story about a blind girl, but have her obviously able to see, but still point out that she is blind, despite all the evidence to the contrary.
If you're going to point out the streams have no audio, and point out the reason there's no audio, there shouldn't be any comments that contradict those statement. It's bad story writing.
That said, it's not like many people even pay attention to the chat when playing this game. Still figured we'd point it out in case it was unintentional.
