Dr. Livingstone transport requests have been disappearing a couple of times for me lately. I noticed since the 3.4 patch, it no longer puts a marker on the map. Sometimes I ended up logging off without completing it because there's no entry in the quests list or map marker to remind me about it. I reported to Hoyo CS but they said that's how it has always been. Weird. Before this I could always see the entry or map marker, as soon as I received the quest. #GenshinImpact
