Old messages momentarily reappear whenever you hit a more prompt in tiles
Entered the tutorial dungeon. When I hit the first more prompt ("you feel that life is rife with new experiences to make (more)"), the first three lines of messages ("The weather is mild and comfortable...") were briefly displayed above the visible messages. When I cleared the (more) prompt, the dungeon level message was briefly displayed above the "There is a stair leading upwards" message. There seems to be some real-time component, as doing the above quickly results in all of the messages being displayed at once.
