Infected spawning the wrong part of buildings?

[Omni17 0]

Date/Time: Somewhere during the night of 6/16 (or very early morning of 6/17). My sleep schedule is too jacked up right now to be able to confirm any specific time.

What happened: Two infected popped out of the wall of a building. It was a building you can go into, but they were inside of a part which players cannot access.

Where you were: NE (Krasnostav) airstrip

What you were doing: Simply walking (crouch-walking) out the front door, and they came out of the wall to the left.

Current installed version: DayZ 1.7.1, Arma II 93701 (it was 93825 at the time of the incident, but I went back to 93701 because of being kicked due to the Battleye script restriction problem)

Since then, while looting cities such as Berezino, I've been afraid to go near the entrance of buildings because I feel like infected will pop out of the walls again. I suspect this has to do with the new fix of infected not spawning in buildings, since it did not ever happen before 1.7.1. And while infected popping out of building walls to attack me has happened in this most recent patch, I have not yet encountered any zombie spawns inside the actual building (the parts a player is capable of being in).
