@crinrictNo effect on scholarship working properly. He's at uni with scholarships appropriately applied. Side note: I tried selling/deleting the letters from his personal inventory (which is where they are now stuck. The letters were automatically in his personal inventory when I entered the game.) They are now not selectable. For a while the corruption also affected my ability to delete his high school homework. (Somehow the homework deletion got resolved when I exited the lot.) He received two additional scholarship letters and there were no issues with opening and deleting them. Don't know if it matters but the corrupted letters are acceptance letters and the working ones are denials.
