Looking at another game, I've been attacked in a non PvP game (though my family does not have the option for any offensive actions against the other one). That's in Efeukirchen - not a PvP game but my hut and walls were attacked by the other player. (I'm not a fan of the PvP way of playing and have stopped selecting them as games to be involved in, so having it happen in a non PvP one is very sad
)
