I have observed a small lag in the 'checking ammo' animation, when your character feels his magazines on his chest. When you start the animation by holding the 'R' button, you can see the hand of your character glitching a bit, almost like it comes back and continues in a split-second.
The last thing I have noticed is that if you spawn while you are choosing your loadout, your character's mouth and eyes (which are seen in reverse) are visible in front of your screen, as if the camera was a tad bit behind where it usually is.
That's all! Hope you fix those small bugs and I wish you all the best for the continuation!
