What is supposed to happen?: Self-explainatory; body should remain visible
Where did you find and/or notice this bug?: Just randomly noticed it while using my buffs in BPQ while using my Marksman

Extra information (optional): After some testing, this only seems to happen with 2H weapons equipped. My best guess is it's related to the WeaponsBehindBack feature (as seen in video, I have it enabled), though I haven't tested to see if this occurs with the feature off. It also disappears once you use any attack, but can occur again when entering a new map. It's oddly specific, overall
