So... This has been happening since Friday (9/17) on my Xbox One X. I'm not sure if it's a symptom of something more critical or just an amusing glitch...
Like many (I'm sure), I sometimes goof around in the Fast Travel ether-world... running, practicing rolling/sliding, and SHOOTING...
Since the Friday (9/17), I've noticed that all the arrows I shoot into the ground stay there between Fast Travels... Also, if I exit Fast travel while the bow is drawn, the arrow will be suspended in that position the next time I Fast Travel... I've been testing it and ALL the arrows from the last 4 days are still there.
