In the village of Bor, as indicated with the uploaded image file, there is a house with a particular doorway that blocks the player.
There are no obstacles to be seen, however the player is blocked when attempting to walk tall through this doorway.
By crouching, the player can pass through this particular doorway.
The doorway seems to only be blocking the player from one side. {F29428}
This is afaik some dev build 0.30.113953.
My player character was wearing a backpack + mosin rifle + firemans axe on the back.
Player character's hands were empty.
Apparently, this issue seems to be with the house model itself, as (afaik) a similar looking house also has this issue with the doorway, however this house is somewhere else on the map.
This time around, my character was fairly new, and only had a backpack on, with a couple of items in the inventory.
Presumably, it is just the file for the house model that is the cause of the blocked doorway.
