I found out a command feature in your history commit, but It is not able to use like /aov prefix in the game. I'm wondering If this is implemented in 1.13.2?

The commit you implemented, but I cannot use any of command in the latest 1.13.2 aov 😢

By the way, What is debugger item used for? I have no idea how to use It 😕

The aov command should be working fine, I've been using it myself in 1.13.2. I haven't tested it on servers however, is this on a server?

The debugger is for my own use.

I have successfully used /aov but I have noticed that when I try to use a player name it fails. If I use it without a player name (i.e. on myself) it works fine.
