Hello, Just tried my Mastery Rank 30 test after practicing it and it glitched out on 3 out of 5. I killed all the bosses and it left a boss tag in the middle of the air and would not let me proceed. I have been working really hard to get here and it seems like I will not be able to complete my year long quest. Please fix this! Nobody wants to work their butt off to get to this point and have a glitch fail their test. Have not been on today except for the maybe hour practicing and doing the test.
