Bridgeport Ride Bugged?

So I’m trying to finish the “Bridgeport Ride” quest which I’ve done several times with other characters with no problems. I ride through the town, over the bridge, and I’m good. For some reason, as I’m trying to do this with my Monk, I get slowed, and knocked off the horse to be killed. I’ve tried doing this quest over several times and the same result. With all my other characters I only had to do the quest once and with no problems whatsoever. Is anyone else having an issue?
