I was recently creating a word list of all the vocabulary words found in BBG by chapter and discovered a format issue in chapter 12. As seen in the screen shots (print and Logos) below μαθητής is hidden amongst the lexical verbiage for ἕως. For those unfamiliar with the book this could easily result in the overlooking of an important vocabulary word.
This is the only occurrence that I came across, but I only combed through twice.
Hope this helps! Just figured I would give a heads up so the issue could be corrected.
