The main point is why I am mad is because he comes into my server, takes my build, and declares he's going to host with it for a "Fallout map" (Probably not going to finish but even hosting with it and making a new game out of it is offensive) So, when people join my server and join his and we have the same build, I'll have to explain what happened, along with he lied to me when I asked him to delete the save if he was going to be hosting with it and said "It's a client-sided mod" apparently he has a client-sided mod that allows him to delete saves from his Blockland folder instantly??? No, anyway, that's bull stuff because that'd be the most useless client-sided mod ever.
