If you move into the VMC Military Camp (Mount Veresnik) you'll find yourself not able to run into the Barrack Building Cell.
At North West Airfield, there's a similar issue, but this time all of the Large Barracks can't be utilized at all.
Besides the examples shown in the video, there's also one civilian building that you are unable to enter because of this bug. I forgot which building that is in the meantime and don't have proof.
