[Predator III]: Captain Wiley
I am having the same issue as well. So far I have spent about 4 hours waiting and map hopping hoping to find Captain Wiley, my last assassination target. The event in Newbeach Bluffs where the buccaneers try to dig up treasure with Mister Floon seems to be bugged as well. Between 2-5 NPCs are just in an invulnerable state.
