Everytime I revive someone including pets while in operator mode while also crouching to become invisible, if I return to warframe mode it gets in a bugged state where the animations are stuck facing one direction, the only way to change the animation direction is to aim a weapon and I cannot use any of my weapons to attack, it will stay this way for the rest of the mission, I noticed that the warframe also become a lot more resistant to damage while in this bugged state and the only way to get out of this bugged state is by dying and reviving myself meaning the bonus damage resistance aquired by the bug makes it harder for you to get unbuged, if an ally revives you it won't work to unbug you, this is especially annoying during archon hunts because I need to revive my allies and the safest way to do it is in operator mode while crouching to become invisible, aka the recipe for this bug and I cannot unbug myself in archon hunts because there is no revives during these missions and that is the only way to unbug yourself.
I notice that if I stand up before returning to warframe mode it doesn't get bugged but there is another bug that keeps you stuck in crouch mode sometimes and you need to hit the crouch button twice to stand up and that makes it hard to avoid triggering the bug, especially in combat where you need to act fast.
I know it's very unlikely this will get fixed anytime soon but at least I did my duty and reported it
