Sorry for my English. I have given all modifyworld's permissions to Default Users and admins , but, mobs don't damage you, they can target you but they don't hurt you. Hungry and fall damage works fine. I have essentials, PEX,Modify,WorldEdit/Guard... Help me please! (Lava doesn't hurt too)
First off, check if you have "mob-damage" set to true. Also check that "invincible" is set to false. Just go inside the region and do /rg info and it will list all flags. /rg flag [yourregion] mob-damage true and /rg flag [yourregion] invincible false will also be of some help. Did I solve your problem? Leave a like if I did! Hope this Helps! Valzu11
