Mastery Rank 9 Test Sneak Attack Bug

[EvilCrazyman]

When taking this test (Stealth Kills) i tried to actually do the stealth attack (behind the enemy, button prompt) and when i attack with my War, the grineer morphs thru me during the animation and detects me which ruins the attempt. i have failed due to this bug 2 days in a row. the 2nd day is because i would be just far enough to not get the button prompt but sometimes i would misread the distance and i would do the attack by accident. I don't know if this is a bug with just heavy swords or if its for all melee stealth attacks. just thought id bring this up due to it being a major pain. doing this test so much is making me moke the lotus' failure voice lol.

The wonky animation fails really suck.

Can I just add, though, seriously screw this test anyway? Even with a weapon that works right, the detection is overzealous, and it goes on for WAY too long. Not to mention that I have watched videos of people taking the test getting away with literally the exact same things that cause me to fail, with a weaker weapon and slower frame.
