Pets missing was bad enough but now targeting is being moved in the middle of a shot

Our pets are a 'maybe I will hit what you tell me to hit', we all get that, but when shots in progress are then moved but not to a 'thing' or 'enemy' but to literally into nothing where you must re-target, that's a game-breaking bug.I die from this bug again and again and again in WvW - and I am sure it's the same in PvP if it is happening to others.

This bug started around Christmas, very few shots missed, but they did miss - stopped in the middle of a shot, but now it's ridiculous and exploited easily.

And for the umteenth time, formatting of the text is not working most of the time... the buttons were used, and this is the result.
