The trolleys are scripted at certain points to move, but If I'm in their path they get pushed to the door and get stuck there. The second trolley in the freezer room was stuck the first time around. The valve got frozen on the wall and the little menu to turn the valve was stuck on the screen. Those are the game breaking bugs I experienced.
Thank you for the info!
We will fix the trolleys issue in our next update, sorry for the inconvenience that caused while you played.
The second trolley issue in the freezers room wasn't actually a bug, you entered, didn't use a lighter and due to the darkness accidentally tried to force open the freezers several times, which lead the story into you deciding not to care to carry the trolleys out of the room, and that task has ended due to it, regardless, that shouldn't happen and we will make it easier for players to find the light switch and not hit the freezers when they enter the room.
We didn't find any case of the valve getting stuck in your video (or maybe just missed it, will look again), we assume you edited it out of the video, but we will investigate into the issue.
Thanks again.
