ORC Bumblebee at the berry stash despawned

[Tywock]

Hey,

I went to farm blueberries it was at night and encountered the ORC Bumblebee for the quest. I'm not 100% sure but we didn't have the quest at that time yet. I ran away, not killing it. I did see it a day later still there.  We are now caught up with the quest and went there, but the boss is nowhere to be found. The quest is not completed, and we ran around but can't find it anywhere. We are now stuck on this quest. Is there anyway we can still complete this?

Kind regards,
