I just had a look at the printed ECM at Rev 21:24 which at 21,24.2-16 "d" seems to me to be incorrect regarding the reading of GA 2814. 

The printed edition has εν φωτι  for reading "d" while it is quite clearly "τω φωτι" in 2814

Although the online ECM is still "Work in Progress" and structures the apparatus rather differently, it seems to accurately represent GA 2814 at Rev 21,24.3 "b"

As a side note ... reading "e" at Rev 21,24.2-16 in the printed edition is, as someone pointed out to me, identical to ER 1 2 3.
