Okay. I found so many base inside a faction claim land. The door was wide open and I was able to walk inside. I wasn't able to build or remove blocks BUT I was able to open chest. So that got me thinking. Now I know that even though it is your faction base, people can still able to steal your stuff. Even if it is above, on, or under ground, the base can still be raided. Step One: Never leave your door open Step Two: Make sure your base is hard to break in It was around minecraft night time zone and I let a creeper enter an open door faction base and blow up furnaces (furnaces is not able to be open so your stuff is safe inside) and I take their stuff. So there are many ways to raid people. Claim land is not safe. Rules #1 Make sure your base is raided proof. Add lots of defense and layers of good strongest shield blocks. I almost upgrading my base so it is almost good un-raidable base.
