Another player and I both ran into the same room at the same time, me not caring started building immediately as soon as I got in. The other player then continued to harass me about how I was breaking the rules. I then told the player that it is not against the rules to build in the same room as another player and he then continued to use profane language insulting me. After, he then prop-blocked my boat making it so that I could not get on. I have included the screenshots below. As you can see, the players larger boat is on top of my door boat.
