I own a server from Aternos. Yesterday I enchanted diamond sword to 1000lvl Sharpness and everything was okay, but later I added few plugins to my server and next day (today) I tried to activate this command:
/give @p diamond_sword 1 0 {ench:[{id:0,lvl:32767},{id:1,lvl:32767},{id:2,lvl:32767},{id:3,lvl:32767},{id:4,lvl:32767},{id:5,lvl:32767},{id:6,lvl:32767},{id:7,lvl:32767},{id:8,lvl:32767},{id:9,lvl:32767},{id:16,lvl:32767},{id:17,lvl:32767},{id:18,lvl:32767},{id:19,lvl:32767},{id:20,lvl:32767},{id:21,lvl:32767},{id:48,lvl:32767},{id:49,lvl:32767},{id:50,lvl:32767},{id:51,lvl:32767},{id:32,lvl:32767},{id:33,lvl:32767},{id:34,lvl:32767},{id:35,lvl:32767},{id:61,lvl:32767},{id:62,lvl:32767},{id:70,lvl:32767}]} but I just received a normal, no enchanted diamond sword. I tried again few times but I was still receiving that normal sword. If it helps, here's a list of plugins I have installed:
AdvCom
DragonTravel
MyPet
SpawnMob
WorldEdit
iDisguise

sorry for any grammar mistakes, English isn't my mother language
