"The game is currently in Beta, so armor is very common, though difficult to come by. As of the recent update in Alpha 0.5, you can no longer loot the corpse. It is now considered a crime and you will lose all items if you try."
Yeah, I was the person who wrote that. To explain, this was done near the Bohemian Camp, earlier the Kolben Estate, and at the battle at the church. At all of them, I attempted at looting a Bohemian soldier's body, out of sight of everyone (except the battle)
In the first instance, I was tracked down and killed for theft (I had robbed the corpse in broad daylight with no witnesses.)
The second I had looted the corpse of the dying soldier in front of his friend. Nothing happened for a while until I reached Samopesh, where the Baliff actively pursued and attempted to kill me. I was able to kill him in turn, but not before three fully armoured knights from the camp came at me and killed me swiftly. (There was a witness to this murder, and I had killed her. The knights only came after I had looted the Baliff's body, but not the dying soldier from the Estate)
The third and last instance was at the Church Battle. We had cleared our way up to attacking the church itself, so I thought, ''Well, the boss is inside. I should get something better for armour.'' (I had watched videos on YouTube earlier and let's just say the boss slaughtered Henry easily, but they (the players I watched) went in with barely any armour and were terrible at the combat anyways) So I decided to loot a fellow Bohemian of his full suit of plate armour. That's when I left the loot screen, equipped the armour, and was killed en mass by all the Bohemian AI that had been up attacking the church.
So I wrote it as a bit of a warning as well as a possible bug. I tried a second time at the Church Battle to loot a Cuman, and got the same result with all the AI attacking me, Cuman and Bohemian alike. Whether or not this was intentional as a derivative from looting corpses or as a bug I'm unsure.
