As of late I've noticed a few things.
After the second patch to 1.20 I've noticed two military zombies stay persistent at the military convoy spot just east of pogorevka/rogovo area.
Still experiencing disappearing buildings or objects such as cars, not quite what it was when everything would be disappearing, but enough to make framerates stick at around 20fps sometimes in any town. And floral seem to be more frequently showing light green graphical rendering problems still, again, not as bad but more often than what used to be.
Thirdly and most importantly, after the latest patch the hand bug making you unable to shoot completely after raising hands has returned. I was using the AUR AX with the 6x48 atog set to the red dot aperture, a 60 round mag, western suppressor, the mossy green helicopter and military convoy spawned ghillie rifle wrap, and a universal flashlight with a battery inside all equipped to the gun. It was the only time I used a gun since the patch. It was just from walking speed and not sprinting, stopping, and aiming.
One other thing I've noticed, I was driving a red gunter with a damaged engine, only one door on the front passenger side and it was a blue door. It seemed that the behavior of lagging? You could call it where the car loses control without traction control loss happened whole driving. This was on dirt roads taking the back way from grishino to staroye and then back. I experienced intended traction loss as expected but also there were a few times I thought I would be flung into a tree.
