Since the S12 patch, when coming out of fade sometimes Moria’s hand/arm is stuck in the default “resting” position for a moment while you use heal spray. After a couple of seconds her arm will then flick back into the normal outstretched position. It doesn’t occur out of every fade and I cannot seem to replicate it with the Mythic or Blackwatch skins (maybe?), but it has been persistently happening since the latest patch.
It’s a minor issue that doesn’t impact gameplay of course, I can’t link a screenshot but hopefully what I’ve described is enough.
