1. Retake the Farm and bring Sprinkler Parts to Clearance
Does not count all Centaurs to be dead. The NPC does neither accept additional parts of Sprinkler after the Event is “done”.
2. Gather ruined Grapes from Victorias Vineyard
Only 4 Grapes to collect, but we need at least 5 it seems. And yes I checked the small field and house 10 times killing 50 centaurs. There is no fifth grape.
Edit: This one ended after I got out fo range towards the abbey. Either one player can only see 4 grapes each OR the respawn time is far over 10 minutes. Both things are not the best solution.
