Whilst not in Valhiem i was trying to get a rare drop in Lostark from Graveyard after 200+ kills of the only mob that spawned it..i gave up and uninstalled.. 240hrs in game but was getting similar delaying.."issues" everwhere.. So i feel your pain there is a delicate balance between reward and frustration.. but hey its EA there may be a bug or a prerequisite somehow missing..
