By-passing metal doors.

How can you defend against this. We built a nice shack 3 metal doors between the outside and our loot, yet 9 hours later, and someone has managed to build a door into a previously built wall

Then proceed to blow up 3 metal doors to reach our loot.

Don’t get me wrong, We always expected to be raided, would have liked to have been their to at least put up a fight. But something feels very fishy here… Why would they blow up a wall, then put a doorway and wooden door in its place? I have seen this to one other house in the area, so think its something they do regularly.

Anyone have any ideas on how to secure against this?

build a metal base they will then go for the doors not the walls
