If I had to pick a single bug, it would be the one that misreports wind speed and direction. In the tundra that throws a navigator into a maze of blizzard‑swept ice and makes the whole route impossible to trust. I’d purposely leave it exposed to test my own skills – if the map says it's calm and it's a storm, you’ll learn to rely on your own senses first. Once I’ve proven the route works without it, I’d patch it back up. That’s the only way to be sure I can survive a glitch, not just fix it.
