Forgotten Bounty at Plunder Point quest crash

I arrived at Plunder Point and set the explosives, pushed the detonator and started with the mobs... then my game crashed, when i returned to the game the Island is now empty, no mobs or NPCs. What can i do? Is my character bricked and will i have to start him again?

Same for me. Empty island and can't continue the quest to unlock the rest of the runes stuff.
