The location posted in the image below is not accessible without crouching when it is accessible on any other part of the ship - such as the rear. This location is on the front half, and spawned a mask. If you try walking toward it from either side, you will not pass. Crouching allows you to get in, but you can become stuck momentarily. There are also doorways, on certain houses where you have to crouch to get through. This is using 1st person mode. It is always the same type of house in the same room. I will post a screen of that house soon. {F30282} {F30283} {F30284}
