Since fixing the issue for every single version is difficult and finicky, and we're already a 1.8.9 version main server, simply make a notification in the chat or in the center of the screen along the lines of "If you're encountering a glitch with the arrows, we recommend switching to a different version, ex. 1.8.9". This doesn't have to be server-wide on all games, but for those games that are centralized around using a bow, since that's where it matters most for obvious reasons. Or at the very least it can act as a temporary fix if it's too unpleasant of a solution, but it's certainly necessary. "Why not just have the Experienced Turfies just type it in chat?" They just won't. I've once had a full lobby of turf pros, including TWL staff, with just one random in the game who was experiencing this very situation, and everyone ignored him; I will never forget that. You cannot trust turf wars players to help their community which they so very much love complaining about the downfall of.
