Occasionally, as I’m upgrading items for the Weaves in the Athanor menu, it starts consuming Athanor, but doesn’t upgrade the item. I’m thinking some kind of backend error.
Here’s what I spotted when browsing it myself, first appears on line 29153:
15:27:36.481 [Lua] [BackendInterfaceQuestsPlayfab] Error from backend when upgrading item magic level: Client cost does not match backend cost
