I know there have been some other recent threads about Rachmaninoff pieces with potential small note errors.
I ran into something recently in the 4th movement of his musical moments (in the attached picture).
The circled note is a D, but every other time this comes up, the right hand plays an E (which also matches the left hand). I was wondering if you guys would assume the D is a typo in this case and just play an E? The piece is very fast so I guess it nobody will really hear the difference, but I'm curious.
