The quest:
The quest ‘Crossroads Caravan Delivery’ has the player enter a vehicle (climbing on the back of the caravan kodo), locking the player into only being able to use the two weapons in the vehicle, and only being able to use them against enemies which spawn as part of the event.
The bug:
During the event, if the caravan passes near hostile mobs they will attack the player’s health directly (not the vehicle’s health). Being attacked by hostile mobs in this manner is highly likely due to the significant number of them pathing near the caravan path. These enemies cannot be fought and they can easily kill the player before the caravan reaches its destination.
Workarounds:
a.) If the player has enough health, they may survive being attacked, however this is difficult to achieve since the mobs now level up with the player.
b.) If the player kills all mobs along the path, it may be clear when the caravan comes through. However this is also a tricky solution, since mobs that were killed before the player cleared the path may respawn sooner, and still others may appear out of the way but later path near the caravan.
c.) The only reliable way to complete the quest appears to be to have a player who isn’t in the event run behind the caravan and pick off enemies–however even this one requires the player be able to stay with the caravan while being attacked by sometimes multiple enemies.
