I started a fresh run for this patch, and when I unlocked the shortstack potion, I noticed that the title display disappeared after the first mirror scry. This made it impossible to tell whether or not I needed to use the potion. Beyond that, I've noticed that milky visual effects seem to linger one multiple different adventurers after certain chest-affecting story events, like the portal bra. It seems to go away after I restart a day or sell a milk potion, so it's probably some kind of flag that's not properly resetting.
Other than that though, I've been loving this update. The titles for each day add a really nice touch to the game, and the custom artwork in place of what had been rough sketches and stock images really helps tie the visuals together! (note that I haven't played since the initial week 4 bugfixes)
