Thanks Kiji! In the next update (not live yet) Humanoid A sends you to 'Where Snow Rose Grows' while the quest is active (and you don't already have a Snow Rose). That map was missing entirely. Drop a May Mist on one of the flower beds, then hit it until the Snow Rose blooms and drops. Beds reset when you enter the map so they never run out. Please re-test the whole quest through to Phyllia.

Marking this fixed. The change ships in the next update. If it still happens after that, please reopen this report.
