Playing the Steam version, and I had just finished the game the night before this patch came out.
The new version of "Cut Your Losses" seems to have a bug, in that I simply CANNOT get it to draw a line from the top-right player to the right-most player. And the solution I found requires a pass between those two.
Also, while the rotation of "Room Key Confusion" makes it easier than the original version, the addition of that final vertical pipe makes it a little TOO easy, to be honest.
Finally, when loading a save file of a completed game in slot 2, the scroll bar for the puzzle archive fails to appear at first. If you click "Back," and then click anywhere to bring up the list again, then it will have the scroll bar.
