I noticed recently (I believe since fixing of the glitch where survivors weren’t able to get through certain open doors) that zombies have started coming inside somehow with no open entrances. Two separate occurrences so far I’ve had of zombies being able to get in through closed doors. Possibly by accidentally approaching from a certain angle or maybe it has something to do with the glitch where the teleport onto the roof. Honestly not sure but for example one of the times it happened I walked into an apartment that has 2 entrances in chernogorsk and closed all 3 doors. The 2 zombies chasing me were stuck standing outside the door and so I proceeded to go upstairs. Shortly after making it upstairs one of those 2 zombies somehow is inside and is coming up the stares to attack me and right after I killed him the second zombie ended up inside as well and came running.
