Good till Exam hung on 16th Verbal question

The test center is in weird location and building is difficult to locate if you are visiting that area for the first time.
The Center was good, Instructor was calm in explaining to me everything, he wished me good luck.
I got a corner seat and no one had the same appointment time so I was all alone in the cabin for 3.
AWA, IR and Quant went well. BUT in Verbal I clicked on submit for 16th question and exam hung. Called the instructor, he took good 5 minutes to arrange another PC. Although no time or question was lost, but that pushed me in panic mode which was hard to recover from.
Despite this, I will be retaking gmat in the same center.
