Is master rank 18 bugged?

[-Ropefish-]

today i tried taking the MR 18 test, i got to the fifth wave killed everything then...nothing. no more enemies. no end screen. i used frost and his bubble casue that would be the easist way to go about things, im afraid to take the test again as if the same result happens then i have to wait 24hr again

Have you tired a practice run in the Sanctuary? See if you can complete it there before you burn another 24 hour cool-down.
