Arca Plasmor Idle Animation bug "The bent arm"

[NymphWeed]

Whenever i equip Arca Plasmor, the idle animation makes the left arm get "bent", in the way that the wrist or arm gets bent upwards, this applies on all Warframes and i initially thought it was a bug for my Wukong only. But after trying it on my other warframes, i could clearly see that the bug kept occuring inside the ship. During a mission, the same animation bug happens.

(Will submit pictures when possible)

Anyone else has seen or experienced this?

I've noticed this as well, the arm that holds the front of it is bent back to front.  As soon as I noticed it, I had to start using another shotty since every time I saw it, it made my fashion frame look fashion lame.
