+// The electronic organizer and password paper reappear in room 500 after they
+// fall into the water when entering the canoe. rm500:init only tests if these
+// items are in inventory. It should have also tested the canoe flag like room
+// 530 does to prevent the vacuum from reappearing.
+//
+// We fix this by only adding an item to the room if its InvI:owner is zero.
+// This is initially zero, then set to ego when getting an item, and finally
+// set to negative one when the item is removed from inventory.
+//
+// Applies to: All versions
+// Responsible method: rm500:init
