Kumos White Dreamcatcher Earrings & Arid Sheets of Plastic Subeta Darkonite Guide to Evil Genius & Nostalgic Charlie Instructions
They definitely were in my inventory, which I checked, after finishing quests had resulted in a cloudflare error. Upon next try to turn in the items, cloudflare again and still open quests claimed, I didn't have the items. ~ 150k spent
Also I'm not sure, that I actually was rewarded for 2 or 3 prior quests, which eventually did finish.
edit: I bought Darkonite Guide to Evil Genius & Nostalgic Charlie Instructions for Subeta Saggi and again the items are gone but the quest is not finished. Another 110k lost...
edit - Kumos finish quests finally would have worked, but it tells me "You ran out of time to complete this quest!"
Subeta worked for a few quests, now it again ate the items (Angelic Donadak Beanbag & Beaubell Buffet Wet Dog Food) without finishing the quest.
I know the Subeta part shouldn't go here, but since it happened simultaneously ...
