On the proofreading: first of all, 95% of all texts are currently AI generated and f'ed up beyond repair. We are working on the worldbuilding and (human written) texts in the background, but it takes a lot of time.
Getting the human touch in there is priority for now, but my current writer is a) not a native English speaker and b) dyslexic so I expect errors here and there. Proofreading will be done of course, but it's a kind of polish that is more appropriate during a beta phase or even shortly before release (which is currently planned in one year from now).
The line "A warm glow emits from the fireplace" is actually from a human writer. Personally, I don't see too much wrong with it (I would file it as artistic freedom), but I'm also not a native English speaker. Anyway, we will do a quality check down the line.
I would say, for now these kinds of errors are a nice reassurance that these particular texts are not written by ai :P But again, once it comes to the polishing phase, we will have a closer look again at all the texts
