I'm in chapter 3 and chose hugs twice (because it's cute and wholesome :D) and the sentence I spotted is about the person Catherine is teaching: "The young tiefling was being able to do everything on her own."
It's already in the past tense, so not only does "being" not flow naturally with the rest, it also breaks the agreement of tenses. Drop it. If you want to emphasize it's only temporary a construction like "this time" would work.
P.S. While I was taught a good deal about grammar, I'm not a native speaker. If my corrections ever feel off, do tell, I'd love to learn and improve. :)
