Guild Wars 2

Apologies if I got the name of the bugger wrong … it’s the boss that pops up at the end of the event to help a sylvari escort some young bristlebacks to a new home. I fought it today, and no kidding it reset four times in a row, almost causing the event timer to run out on us. Nobody was running away from it like a headless chicken, instead it apparently reached its leashing distance just by doing its own charge attacks.

Were we just really unlucky, or has anyone else encountered this?

I encountered it last night. Not 4 times, so I was able to finish with time to spare, but I suspect your theory is correct about his own charge doing it.
