Random leave buster bug?

I am very confused i recently just finished a 45 min game and as soon as i finish honoring someone a message pops up saying leave buster then my client crashes??????? so after i play a full 45 min game without leaving and saying no to ffs i get a leave buster? that is frustrating, and i haven't left any games at all since November of 2017 and its feb 19th 2018
