So, I use world guard and world edit on my server. There are two command options for blocking spawns: "/rg flag (name) mob-spawning deny / allow"> "/rg flag (name) deny-spawn (mob)". I want to block an area for specific mobs, so the second command would be more coherent, however, it didn't work with mo'creatures mobs, the following message appears: "org.bukkit.entity.entitytype" Is there a plugin or other way that I can use to reverse this situation? I'm new to this forum and I don't know if this is the correct page to post this question, so I'm sorry if I was wrong.
