I thought I heard something about this before, but I couldn’t find it. Anyway:
Summary: At the beginning, after the banner is placed, the player is not told to place a stockpile. In previous versions this happened and so I am assuming that this is a bug. Furthermore, it looks like there are two sheets of paper at the beginning, implying that it is meant to be a feature.
Expected results: After placing the banner, the player has to place a stockpile.
Actual results: The player can just play normally, and none of the forced-stockpile-placing UI appears.
Notes: This has happened in all of my games (r110 and r114), and also in @Phagocytosis 's videos.
