My puzzlement about MISTY/MISTS is that the clue is one with a definition misprint (lazy/hazy) and with wordplay that gives a wrong letter for the entry (S in stead of Y). The preamble says that the clues are (a) normal OR (b) have definition misprints OR (c) have woedplay giving a wrong letter in the entry. 44a appears to be BOTH (b) and (c).
I don't have all the letters of RHOMBUS, which people here say is the further item, but if it is, I don't see how the correct letter for 44 (ie Y) contributes to RHOMBUS
I did have AGUISE, not AGUIZE. That's two homophon clues where the answer/entry is ambiguous, the other one being 41d. That is poor clueing.
