Melee Disabled (Glitch during mastery test)

[HydroFreeze1998]

I go to take my mastery rank 19 test. The one where it's melee only, and I'm unable to do it due to not being able to melee. And this isn't the first time. Been stuck on this mastery test for a week now because of this dumb glitch. I don't know how it happens. But the only way I know it has happened, during idle animation, the weapon has no sound and has no trail (even with constant weapon trails turned off). That's the only way I know it happened.

Do it as fast as possible. From my experience, this glitch actually has a "inner timer" or something. It usually stops working (with redeemer) on second try (because I always forget an enemy the first try since I'm trying to go as fast as possible). Just do it as fast as possible man, I still didn't manage to do it yet.

Found the reason why.

Wall hanging during the mastery test 19 causes the glitch to happen. I bullet jump, then wall hang, and boom. I also did just jump then wall hang and my melee was disabled. So there you go. That's how you avoid it. If anyone passes by close this topic.
