DayZ Livonia DLC 1.24 update standalone, on official 1st person only server 4295.

Me and my friend were at military area near branzow castle. We attaked 2 isolated infected durying a rain with melee, no other infected on sight. Suddenly almost every infected in that military area were agroed to our location. We ran into the industrial garage building and started hiding from the infected. Even though being completely silent laying on the floor all of the infected continued to be agressive outside the building. We confirmed that the infected were agressive through the building since if we moved inside the building they would follow instantly to that corner of the building where we moved. We waited total of about 15minutes and none of the 15-20 infected that agroed to us stopped their agressivenes.

We found out that some times infected spawn right infront of us (about 10m) when in these kind of areas.

We logged out of the server for 15 minutes. After logging back to the server most of the infected had despawned. We could not varify if the building was still not working as hiding place.
