I was playing disco's Archery mini-game but could not get a single hit. The fully charged arrow was released, but the arrow trail was headed backwards. The arrow landed behind me for a second (I turned around) and disappeared promptly. The disappearing did not happen sometimes, and sometimes the arrow's speed and height would be reduced and it would land just right in front of me. Afterwards, all arrows fired would bounce backwards, no matter what world I was on.
PS This also happens in Creative Mode.
PPS Sorry if this is a dupe, I can't find another similar one.
