Just making notes here to maybe zero in on this bug. Note #1: I, personally, have the auto-turning off. Note #2: Underlined the bit of text that matches, exactly, when the bug happens for me. It can also happen after moving though if I was auto-running and re-position my direction with the mouse; never will do it if I just tap/hold a key on the keyboard to turn. Note #3: Just got done playing for a couple hours and only harvested for the first 90% of play: the bug happened 0 times. The last few minutes of play I killed 20+ mobs and the bug happened *between* combat ~10 times.
