-I've got one more safe left to find, but a memo suggested that might be in room 46--I wonder if it's behind the map that I can put pins in. I won't know the order of the pins until I've solved the last realm sigils, though.
-I've got two sanctum keys left: the last room of eight and the king on his throne. I suspect that the first one might be the eighth door of the mechanarium that the room description mentions, but I've drafted a mechanarium with all the mechanical rooms I have plans for, plus the rotunda just in case that counted as mechanical, and I only counted seven doors. The list of trophies in the entrance hall says that I have one more room plan left to find, so I'm hoping that one's mechanical. I thought the king on his throne might have something to do with the chess puzzle, but I've solved that twice now, most recently taking the king bonus, and no sanctum key. I don't think I've heard any other kings mentioned, so I don't know what else to try.
-I've tried everything I can think of to find the third microchip using the clues from A New Clue (I've already found the one buried by the bridge), but nothing I try is leading me anywhere. I wondered if it had something to do with the LeeB admin key, but the only thing of substance in the fake admin logs is that one of the fake conspirators was hiding out in the schoolhouse. I've been over the schoolhouse with a fine-toothed comb and every tool I can think of, but nothing. I thought that the note on the blackboard about "a timely manor" might be something, but I drafted a whole House of Tomorrow, including a clock tower, and nothing changed in there. All I'm left with now is thinking that the "DEAD end MAJOR KEY" note in A New Clue might refer to something other than the orchard sundial, but none of the ways I've tried to use that to find a second message hidden in the library books has yielded anything.
-I've filled in most of the letters in the "CASTLE" diagram in the chess room on the cliffside, but I have no idea what that puzzle is even referring to.
-I haven't aced the final exam yet, but I think I might need to wait until they release the accessibility update before I try that one again: I'm not sure I'm differentiating the colors in the math sections very well. I can tell them apart when they're being used in the dartboard puzzle, but the shades are harder for me to distinguish when they're just in the small spaces inside the printed numbers. Anyway, I kind of doubt that this is the clue that I'm missing that's keeping me from progressing: solving room 8 just led to a trophy, and I suspect that this will be the same.
