+  (agent) Fixed: loading a world now clears the cards in the lower right, so cards from the
+  world you were just in (Welcome, first milestone) no longer carry over.
+  To check: make a new world, quit to the title, load an older world from Worlds. No Welcome
+  or milestone card should show. A brand-new world still shows its Welcome card.
