Hi,
I started playing black mesa yesterday. During the we’ve got hostiles chapter, I knocked a turret over with a grenade and it managed to get stuck in a blast door that closed on it. Using the button to open the door didn’t work and I couldn’t dislodge the turret with the crowbar either, meaning I couldn’t progress further into the level as the way was blocked.
I also took damage when I touched the blast door.
wasn’t a major issue for me as I had a quick save not far behind that point so I just repeated the area carefully knocking the turrets over 
.
Just thought you should be made aware
