So this has happened in the past, but today it happened three times to a friend. I was commanding a cart drawn by hell horses. In the cart a friend sat as passenger and during our trip, each time an animal aggroed her, she would get hunted (randomly) , village rep raised by 10 points every time. Got 30 points village rep today from this bug. What gives?
Each time a passenger embarks on a cart pulled by hell horses and we aggro a mob, the passenger gets hunted and raises village rep. Doesn't happen 100% of the time but maybe 1/3 mobs that passenger aggroes turns out in hunted status.
