I have had so many Aerotech single use motor cases have small raised area or soft spots over the years in several different styles of casings, I can’t count. I was never worried about it, it’s likely caused by the delay burning after the propellant has burned out and exposed the liner, but the casing isn’t holding pressure, so won’t burst.
