there is a weird problem with amx_llama. When you llama someone and they leave, someone else that joins gets llamaed. From what I've seen, it's random people who get llamaed because the person who got llamaed in the person isn't in the server anymore.
Also, when you type amx_gag in console, it doesn't show how to use the command.
I would love to have the llama option fixed because llamaing people is the best!
